I’ve had a Rytm since they were released and I love writing stuff on it, but I don’t like ‘playing’ it. TR-8s seems much more improv-friendly. I’ve also been giving the Digitakt a go, but again don’t enjoy ‘playing’ it (I’m not into the CTRL-ALL mess-everything-up vibe, which seems to be about the one ‘live’ trick it has up its sleeve). TR-8s and MPC 1000 are really looking like a nicer combination to me than Rytm & Digitakt, but I’ll wait till I can try a TR-8s out in a store before I make any moves.
The fader bug is a little off-putting, but it seems like it could be fixed. I tried throwing 4+ track level CCs at the Digitakt from a Launch Control XL and though it never messes up the timing, it takes a good 1.5s to ramp all the track levels from 127 to 0. But this is what track mutes are for.
