I was always a huge fan of 4.2, its my favorite of all the Froyo roms. And now 6.5 is my favorite of all the GB roms. Idk if me and actn/mojo have similar Droids or what, but everything they do makes my phone run like butter. And I love it.
I installed the unthemed version and the v4 800 kernel... and the only issue Ive had is music will occasionally skip if I have a few apps running in the background with it. Its a common GB issue Ive had, but is really hardware related (not enough memory). Ive found that Swapper2, using the partition not the swapfile, helps a great deal.
[Changing the kernel Ive heard helps too, I just havent gotten around to testing that theory. The new kernel runs a tad smoother for me than Chevys. Im not really sure which gives me better battery, cause my usage changes all the time. And I havent properly fixed my battery stats in... way too long. lol]
The best GB rom out there, and im sure v7 will be even better. Looking forward to it.
