Ive been using BB.4 and its been awesome with no problems at all. I dont see a reason for me to even move to BB.5 since its running so well.
I am new to using custom roms. I have tried UD7 and UD8 for a month and had all sorts of issues such as forced closures, slow performance, frozen to the point I could not use my phone. I had all but given up on custom roms and contemplated unrooting my phone because atleast the factory image was stable. Then I read about Bugless Beast v0.5 and decided to give it a shot. Thus far my phone is extremely stable, has great performance, so far not a single forced closure and I am able to actually use my phone!
For now I will stick with BB but after hearing about LFY and CYN6 I might have to give them a try.

Anyways, this rom is amazing, there's SO many things you can do on it! Try it out, you won't regret it! Shadowrom.com !
