I was leaning towards the quattro USB. Are you saying you've NEVER been
able to record four channels without dropouts? Are you guessing the PCI
version (whatever it's called) would have fewer dropouts with jack?
I don't think, that this is what Patrick meant. USB is not really
suited for very low latency applications because of how the bus
handles the data transport. But with a bit higher latency settings, it
is no problem to record or play 4 channels without dropouts on the
Quattro. Nevertheless PCI is better, but not an option on a laptop.
For a standalone machine, I'd highly recommend a 'real' card.
Another thing about the quattro is that even the windows drivers will
not allow you to record and playback on all 4 channels at one time.
You can use
4 in, 2 out 48khz 24 bit
2 in, 4 out
2 in, 2 out 94 khz 24 bit
I think I am running up against this with my latest attempts. It may be
that the quattro cannot do all 8 channels because of a hardware switch
maybe for power consumption or something. They do run awfully hot and I
can imagine that it would be possible to melt something if their is too
much power running through them.

Being on stage with the band in front of crowds shouting, "Get off! No!
We want normal music!", I think that was more like acting than anything
I've ever done.
