well, there is also bonus map pack, the point is that when I was newbie I mostly practised on nc/nail mappack meanwhile bonus mappack didnt out yet, those are awesome to play, you feel them good and they are pretty simple to finish, eminef/azo1 feels very good too, but they are harder, fluffy (from 101-151 maps I guess, 2nd pack) feels awesome as well, but they are tighter and harder them emin/azo1 to finish, also angus, i would put it between emin/azo1 and fluffy
