Quite honestly, I think 5.0.8 is pretty snappy myself. I have it overclocked with JDFG's 1.2 kernel and it is smooth. Obviously, its not as fast benchmark as 2.2 but in everyday use I don't notice it. I jump around so will be back on froyo soon enough, but i like the transparent app drawer and phone with ADW on 5.0.8 wish someone would make that work on a froyo rom
5.0.8 is better than any Froyo rom out right now. CM is stable, you don't have to worry if your phone will randomly reboot while using and app or if your browser will freeze on you. The only thing that Froyo roms have that is hurting CM right now, is Flash. Once the 2.2 source officially comes out, CM 2.2 will be the best out and everyone will be jumping ship.
