Same thing... All JACK does is basically move audio samples between
sound cards and applications. What that means is that every device
involved must produce/consume samples at the same rate.
The only way to overcome this is resampling, but for good reasons JACK
won't do that unless you ask for it (by using alsa_in or alsa_out).

More importantly, you can only use two sound
cards with JACK at the
same time if their sample clocks are synchronized.
Are you sure this applies to using different cards for recording and
playback?
I assumed it mostly mattered when trying to record from multiple cards (not
that I have ever tried any of the scenarios :) .
