I'm playing 3.2 and I like it.

I've been playing LTC also, but I'm doing a Portugese SS campaign as I was waiting for a couple of fixes with LTC to be finished.

I've not had any problems with SS so far, very smooth, AI is pretty agressive, especially if (like me) you take a more passive approach to the game and don't blitz (which is harder - SS has a few more cities added in, and most of the rebel cities have enlarged garrisons).

I don't *really* like the Knights Templar, but they're not the easiest faction to play either, starting with one castle in the middle of the holy land - however the one diplomat by Rome certainly adds a 'get-out'.
