Well I dont own any of these cards personally but I cant make suggestions based on what I have read, heard etc.
It all depends what you need.
Aardvark Q10 - it is good but expensive mainly due to the fact that it has so many phantom powered XLR mic slots. Sonically I dont think it is any better than the Delta etc Do you need to mic lots of mics at once?
Delta - very good card. Lots of jack inputs and outputs but it mainly deisgned forn use with a bog mixer ie. an 8 buss mixer. Although this is not essential by any means. That is just the idea behind it you understand. It has no XLR slots so you would need a mic preamp/mixer if you are going to use a mic/mics esp if they are condenser mics.
Digi 001. Same as Aardvark really. It is really designed for Pro TOols though and also for use with Macs. Other users of this would need to commend as I read one post further down in which someone made out that it isnt compatable with any other software! This would make sense. Digidesign stuff is all proprietry.
