I was in the same boat as you recently and I decided on an 55 S60. The smart features were useless to me, anti glare would be helpful but unnecessary in my basement, and like you I'd be using the panel mostly for gaming with occasional movies. I watched a few movies last night and the PQ was fantastic especially for the price (55'' for less than $1K). I'll be picking up a PS4 once the exclusive games start coming out, but I can't comment on the input lag other than the tests from around the web at 34.1ms on the S60 vs. 73ms on the ST60. There's a few videos on YouTube claiming no real issue with gaming on the ST60, but this is always subjective to the player. For me, I'd rather save the $ and stick with the S60 + calibrate after 100 hours -- have no worries with gaming and still get awesome PQ. Good luck.
