[Q] What is the Fastest/Stable Available Right Now? topic

Hi Guys, so i'm putting my LG G2 down for a second and picking up my old P705. Why? because i'm wanting to use it as a dedicated device to complete some tasks that I am setting it to do.

So what I'm wanting to know is what is currently the most stable and fast ROMavailable? I haven't been in the section for a long time so I have not idea what i'm looking for.

Any help would be much appreciated
Thanks :)
