[Q] What is the Best JB Rom for GT-N7000?

Hello XDA!

Let me start by saying THANK YOU to you BRAINS out there that make our world better!

Now, who can please advise on the best JB ROM to-date for the GT-N7000?
by best I mean: battery life, features, speed, no RAM problems, etc...
I'm on RR v3 now, not sure if I should try Ultimate.

I'm sure many of you have tried every ROM out there... let me know your thoughts please!

Thanks,
Elie
