Does having a more diverse map pool (downloading and playing every map you can) leave you with more experience than gathering say, 50-100 songs that you enjoy and continuously practicing on those? (difficult songs if I may add)
50-100 songs is plenty enough for a long time, but it all depends on what you enjoy. If you can play songs you don't like, but enjoy ranking high on them, then the value of fun is what matters in the end.
I'm saying this because having fun usually makes you improve faster.
