anyways: an analogy:
when i first started to play guitar i thought clapton was the greatest guitarist there ever was (not completely based on nothing), but then i heard hendrix and van halen, then i heard malmsteen and petrucci, and my beliefs keep changing with everything i hear.
my point is don't limit yourself like that. nirvana was good and they brought a new type of music, however, as far as talent and songwriting goes, there are better, but it is my opinion, and this is yours. so believe what you want.
To improve technique and of course trying to keep all as clean as possible. I know my own limits and speed limits and so on I never play anything I'm not capable of. That wouldn't make any sense. After three years of playing I tried to play everything as fast as possible and that sounded, I would say, like shit, and I didn't realize that if I'd play bit slower things than I was capable of playing then everything would sound much better.
