I went to 6.5 haven't looked back. Innately the OS is more efficient than 6.1 IMO, keeping up a sleek look and being generally more responsive and managing the memory better.

On top of that, I use Juicy 7, plus SPB mobile shell 3 an I couldn't be more satisfied, the only qualm I have is switching from portrait to landscape takes a second or two, but I definitely won't be going back anytime soon, the start menu is better, titanium (even though I don't use it), is infinitely better than the original 6.1 interface, and TF3d is just kind of eh to me, I like the feel of 6.5 and SPB together, I really feel like ms needs to partner up with them.
