[ONE Q&A, Help & Troubleshooting] critofur:
I've spent literally days and days reading through threads about various ROMs, I'm hoping someone who has more experience with OPO ROMs than me can point me in the right direction - looking for a solid ROM with these features baked in:

Good ad blocker

Privacy guard

Best or close to best battery life

Can set system font

Solid : doesn't crash or have nasty wakelocks / memory leaks - want a phone that spends most of it's time nicely SLEEPING when it's in my pocket

Most of the ROMs I've looked at seem to be missing one or more of those basic features? I was thinking CM 12S will be good, but then was reading about layers and they were saying the CM theme engine is not so good in terms of security or efficiency compared to the layers theming system?

I like CM 11S pretty well at this point, but I realy want to get behind (support/use) a great ROM that comes with something like AdAway pre-installed because I want to see good ad blockers included (built into) more ROMs and I want to support that. It's deeply discouraging to me when I can't find a great ROM with ad blocking baked in. Same with Privacy Guard - I don't think any ROM should come without Privacy Guard or equivalent baked in!!!

Thank you so much for your help/advice - believe me, I HAVE searched and read many threads, but I expect there are thousands of other people who have had their OPOs for weeks or months longer than me and can give me some solid advices! :)

Please resist the urge to simply tell me "Just try ROMs for yourself bro!" - I have done that before (on my Galaxy S3) I probably tried about 30 - 40 diff ROMs on that phone. At the moment, I look and read when I can, but before I flash I'd like to know if there are least a couple that at least have those basic features, and if not, I wonder why?

My best guess at this point is, I will need to stay with CM 11S and ad Xposed? I used Xposed a couple different times, but most recently it broke - the device still works, just Xposed was no longer compatible once it got an OTA update... I haven't put Xposed on my OPO yet as I didn't have much time for making backups/restoring re-flashing the phone in case it gets messed up because I have my kids over spring break for the next week and a half.

The only issues/missing features I'm currently experiencing with 11S are: haven't figured out how to set my system font (or perhaps my old type of font file is no longer compatible?), don't have adds blocked in apps yet, and I want to change the color of my clock in the status bar. I will go ahead and read through threads about putting Xposed on OPO - hopefully it can be added on 11S without causing any glitches?

Oh, and my [stock/unlocked/rooted CM11s] phone is not yet working for LTE - I have Walmart Family Mobile and I recently read that they have begun supported LTE. Sometimes it's just 3G and sometimes it's H+. I will call their support sometime over the next couple days because so far all I did was move the SIM card from my S3 to the OPO and perhaps it's not properly "provisioned(?)" for LTE yet? I say that because I watched one video on Youtube where a guy had to take his OPO to the AT&T store and put his SIM card in another LTE phone, then when he put the SIM back in the OPO, LTE started working on it.
