I would say the UFX1204 would use the same chip as the UFX1604 but in the UFX1204 Channels 13/14 are if you want to record your AUX Channels, and 15/16 are for recording your Main LR Mix.
If you want 16 separate inputs use the UFX1604.
You can get an 8ch preamp with XLR/Combo's for the other 8 lines if you like.

EDIT: Just get a fast write USB 3.0 Memory Stick like ScanDisk, this will let you record 16 @ 24/48.

Yes, stereo USB out mixers are useless, that's what PG use to record their drums, so you are stuck with a stereo mix that can't be edited or drop in like Mario mentioned crazy
I think I will get another off eBay but get it sent to:
