Look, OK... Kits is AN answer... Better?
What is the question, though?
Want our current level of control, editing ability and flexibility? Loops cannot give us that. So, to gain a tenuous increase in audio quality (again, simply go to those links I posted and marvel at how LIVE those MIDI tracks were - you DID notice they weren't audio loops, didn't you?) you give ALL of that up. I don't see this as a solution, merely substituting one problem for another.
All I tried to point out was, MIDI percussion CAN be almost indistinguishable from audio loops nowadays. So why would anyone want to use loops, and lose every single editing ability we currently have, AND the ability to use the improved sounds on styles we already have, for something as preset as loops are?
THIS is why I consider kits as the answer, not loops. One step forwards, if you have to take one step backwards too, is no progress at all, IMO. FAR better kits is a step forward with NO step backwards. Hence, why I consider it the answer.
Perhaps, you might suggest something that has NO drawbacks, if you have a different one?
