I like 'em both. Original Toy Story broke serious ground in terms of ray-tracing animation. TS2 is the rare sequel that actually takes the original story to a new level, not just give you more of the same. I'm looking forward to TS3, but with guarded expectations. It's hard to revisit a franchise after such a long break and score gold again, but Pixar isn't just any film company, so it's entirely possible that it'll be another winner.
