Heck, I love LA2 for just the soundtrack alone!  One of the best chip soundtrack's IMO.  But I ultimately prefer it in general to LA1.  LA1 is great, but a bit harder, & a littler unforgiving.  I think it's mainly trying to land on platforms in some spots that bugs me about LA1.  Ofcoarse, LA1 has a great soundtrack as well, but I'm quite partial to the sounds of LA2, Dungeon Explorer, Bonk 1 & 2, & Twin Cobra.  There's also a wrestling game that uses the same sound scheme, though I always forget if it's Maniac Pro Wrestling, or that Monster Wrestling game.
