Matter of taste and music, but for wicked hardware techno MFB kicks are just incredible. I’ve only had a little experience with Tanzbar but liked it a lot, very tight and pleasant bd (2x!), but I use samples of MFB kicks almost in every track, really like Shlagzwerg modulated samples, they’re insane! To me they have right balance between being „full“, not too annoying, and always sound „exotic“.
Other than that I find Digitone kicks quite useful in IDM / glitch music, feel like good samples : )
Remember Jomox XBase kicks - yeah, but… never fit to anything, too huge

Still want to try Alphabase at some point.
Most of the time I have 2-3 kicks in my tracks - the main is usually 909 or 808, they just work, the second makes „bass“ in empty spaces that’s where MFB or Jomox or Modular can be perfect (or tuned 808 ).
Another story - DSI Tempest. Never liked its sound in a studio, really need a lot of processing or tweaking, but in the club it sounds very very nice, almost the best live drummachine I’ve used (on pair with of 808 or 909 ) in terms of sound. Can be lush or nasty. Very cool analog vibe.
DR-2 not sure. Very pleasant to play with, in the club it hits ok, and I record it often, but still I usually replace DR-2 kicks in my tracks with samples. Maybe too „midrangey“, not sure… Need to spend more time with it.
