Reply to performance controller assistance

So, i'm trying to get started with making my own tracks, have some really good libraries picked out, just stuck on which controller to run with.

I plan on using ableton Live 8 and various VSTs

my choices:

Novation 25 SL MKII
Akai APC40
Native Instruments Maschine


I would like to use it live as well as in the studio. pros and cons?

Thanks!
