Well, I guess I'm a tad late... :-/
But either systems are good, it depents on the setup.
MotU ain't as good with the drivers and seem to loose the market-war against DD, so, I would go for the D002R, as it's futerproof (as most of the ProTools-hw is) and the ASIO-drivers seem to be stable under Steinberg and Emagic Sequencers as well.
Although, you should ask for a definite answer about the driver-thing (name the salesman your sequencer and version
and he might be able to look the latest product-info up), cause sometimes the ProTools-stuff is a bit ... erm .. exhausting ...
(Mostly when trying to set up the ProControl onto Logic, the stuff without control-functions work together quite easily).
I have to say though, that I don't know too much about the 896.
I would just mail to them directly, asking about driver-support and what sequencers it works with, if there were common problems aso.
