[EVO 4G General] djs415:
Though my post count is considerably low, I have been an active follower/participator in the XDA HTC Evo 4G community for quite some time now. Remembering how overwhelming it was for me when I came to this website, seeing all the wonderful ROMS as well as confusing information, I thought of how much I wanted somewhat of a welcome post to tell me the best of the best ROM wise so I could jump right into the action. For those of you who feel the same way, I'm here to share my opinion of the two greatest roms currently out right now. I determine if a ROM is great with the following criteria: Stability, User Interface, Eye-Candy, Speed, Battery Performance, Extras from the Developer(s), and most importantly, the support given by the developer(s) as well as other enthusiasts. At this current point in time, these two roms are:

(The following explanations are quick summaries, rather than full reviews of the roms.)

Syngergy-Kingdom Nightlys developed by Virus among others (see credits on linked paged for others involved in the making of this truly awesome rom)

In your travels throughout this website newcomers you will become aware of nightlys as a term meaning experimental, but lacking stability (most of the time).

I can say from first hand experience this rom is the fastest I've seen, with very few problems and a wonderful support community.

Finally we have

Synergy developed by Myn (as above, see credits)

For those of you who have no prior experience to the htc evo modding scene, I can whole heartedly say this should be your gateway flash. Now in it's first release stage, it is extremely stable, snappy, and beautifully designed. Myn, a veteran developer, has been making roms for quite some time, his MO being ease of use and power. Have a question? The support given by Myn or his followers, a.k.a Mynions, is superb and you'll surely find an answer to your problem in no time at all.

Keep in mind, every rom has a different User Interface, and these two happen to be using the Sense interface created by HTC. Though you have the option of AOSP roms, which are very similar to just the normal android experience, the Sense experience thanks to all the developers on this site has become very streamlined, graphically astounding, as well as battery efficient and speedy. In fact, I have run into many more problems with AOSP roms than I have with sense. Just my two cents (no, I didn't use sense :P)

The last advice I can bestow upon anyone new or old who has made it to this final line is that reading is your best friend. You may have heard this way too much, but it's no joke. Just by going through the last couple pages ( I sometimes even read up to 10 or 20 pages back from the last most recent page) of a thread/post can you not only stay up to date on the current rom you are using, but learn a plethora of information about kernels, scripts, mods etc... overall anything that can benefit you. A plus side is you may even become addicted to reading such things, almost as if you're waiting for the new episode of a show you watch weekly. Over and out.
