[myTouch 4G Q&A, Help & Troubleshooting] unhappybirthday:
After 6 months of reading and learning on XDA, I finally got the courage to S=OFF my MT4G and load up some ROMs. So in the past month I've gone from:

STOCK Froyo

to

Royal Glacier (thanks TrueBlue_Drew!)

to

STOCK Gingerbread (Faux123 kernal)

to

Virtuous Unity 2.37

to

Virtuous Doubleshot 1.1.6

Lovin Cm7!

Holy no sense... Batman.

I just flashed the latest meXdroidmod Chili AIO on my wife's MT4G. Now I understand the hype over CM. Awesome ROM!

This is my first no sense ROM. Can't wait for CM7 for my Sensation!

im currently running Virtuous Unity 2.37, its very good if you want your phone to be stylish, and the rom is way better than the stock rom, if you want your battery to last longer than you can download setcpu and set different clocks for locking screen and etc. i currently have my phone clocked at 900mhz and 200mhz on screen off (rounded to nearest hundred) very good rom i rate this rom a 10 out of 10

Virtuous Unity 2.37.

If you want a reliable rom with everything working other than mms over wifi "which I don't use anyway"

This rom is for you. The ui is sweet!

I rely heavily on this phone for gps, bluetooth, remote desktop and exchange.

New to flashing roms so still tring new ones

First one was Virtuous Unity 2.3.5 and loved it! I also flashed the Unity v9 kernal on it. fast great battery life

Next I tried Virtuous Doubleshot. really liked the rotating rosie but only 5 homescreens.

Now running MexDroidmod very fast and great battery life. Nice animations but they got on my nerves after awhile so I turned most off.

Now what should I try next........................ lol

Try Virtuous Unity. Its 2.3.4 GB and Sence 3.0 with all the good stock stuff and the crap removed. also titanium backup is a great help when you keep tring new roms all the time. lol

[myTouch 4G Q&A, Help & Troubleshooting] guythmike:
I've been switching between a few roms lately: cm7, miui, and lately iced glacier. The latter came closest to what I'm looking for, as I liked a lot of the features on the stock gingerbread, such as facebook sense (and the syncing of contacts it provides), faves, and other small things. Iced is obviously out dated and seems to lack a lot of the customization as cyanogen and miui. I was curious if there was a more current rom that has a lot of the features of stock gingerbread but with the customibility of a rom on par with cm7. Like I said, I really liked the sense and faves app/faves icon at the bottom toolbar (iced had it replaced with a web icon, even though I saw a picture and youtube vid of it with the faves icon) that are in the stock, so I'd like something with those. Thanks for any leads/recommendations!

[myTouch 4G Q&A, Help & Troubleshooting] sunsean:
I guess we must have pretty different set-ups, because so far LPP has been working smooth as butter for me. Granted I'm only using 5 screens, but they are loaded with all widgets. The only apps I have are the 15 in the 3 dock rows on the bottom. Scrolling is smooth, pinch-out view is smooth. The one thing I have noticed is not after charging, but after rebooting phone or just powering up in general, it can take like 20 seconds or so before it settles. But I think most launchers take a little extra to warm up when first powering on. Anyway, glad you're happy with Sense. Honestly the only thing that made me hesitant to switch were the great widgets, which is why LPP is my perfect solution.

MT4G + Royal MIUI + Faux's BFS LV kernel
[myTouch 4G Q&A, Help & Troubleshooting] wickedny15:
I still don't think you understand what he means about integration. Your focusing yourself on the home screens which is just the launcher. Obviously LPP runs fast and great on GB, heck I think its even faster than sense home screen I believe. What he means about overall integration is how the UI fits in every setting or application. For instance, the dialer in sense is far better than the stock GB (CM7). In sense you have the dialer along with your recent calls on the same screen at the same time, with one swipe down you can lower your dialer to see more calls and with a swipe up you can raise the dialer. Also, you can start typing someones name on the dialer and it starts listing everyone with those specific letters you have chosen.

Another great integration is the sense camera, it offers more features and effects than stock GB (cm7) and does it with style with a nice UI.. thats what also got me to leave CM7, i use the video and pictures a lot. Also, not being able to silence that nasty GB shutter noise is really annoying.

There are more features he mentioned that makes using sense more pleasant, like what he said about contact pictures and contact profiles, etc.. Everyone has their own taste, so if CM7 floats your boat then thats great! But when it comes down to integration and features Sense is just far better than using AOSP GB.

@ Jack_R1 - if you like sense, then you should try Royal MIUI. Its like sense but much much better and looks a lot more cleaner and polished. Has so much customizations and a lot more integration and features than sense. Oh and more importantly its GB 2.3.3! I went from sense to cm7 to sense and now to MIUI and haven't looked back ever since!!
[myTouch 4G Q&A, Help & Troubleshooting] Jack_R1:
I have bad close-and-not-personal experience with MIUI. I have a friend at work with Nexus, and I installed MIUI for him a couple of months ago. At the beginning he liked it a lot, after a month he came to me and asked me to install any other ROM but this. When I asked him why, he said that it looked ok at the beginning, but there are so many small things not working properly for him, that he just couldn't deal with the ROM. And he's not very demanding with his phone, so I'm just avoiding the unnecessary experiments, having a stable running phone. Coming from Nexus, I've tasted GB before most, and I grew to dislike it completely. IMHO, it doesn't have absolutely anything to add to what Sense already has, besides cool screen off animation.
[myTouch 4G Q&A, Help & Troubleshooting] sunsean:
Totally agree with you guys regarding sense's integration into other non-launcher elements of the phone. I also prefer sense's camera and dialer apps, hands down. I guess it's a pros/cons thing as to what's most important to the user. For me, since switching to AOSP gingerbread, my phone has been running much smoother, more efficiently, and with better battery life, and I like many of the little cm7 tweaks to the system (lockscreen etc.). For me, at least at this moment in time, it's overall preferable to the more-visually-appealing-but-bulkier-and-clunkier sense framework.

[myTouch 4G Q&A, Help & Troubleshooting] radamo:
I have been using Royal Glacier 1.3 as my daily driver for a few weeks now. I was using CM7 nightlies and stable build for over a month and a half. For me sense is better due to the following:

1. Dialer using T9 against my contacts (Dialer one was okay but not great)

2. Email is HEAD and SHOULDERS above stock and blows away K9. I bought and used Enhanced Email for $10 since it included many of the features I needed but had repeated formatting issues.

3. Silly as it may seem I REALLY like having a different photo on my lockscreen than my wallpaper. I used Widget Locker with CM7 to fill that roll but now that is one less app that I need to have running.

I really liked CM7 other than those issues above... and the pull down power widget in CM7 and the ability to set quiet times were great features...
