I think Tempest and a decent sequencer would be my choice if I had to pick just one drum machine. But for some styles I would struggle to choose between a Tempest and an Alpha Base. Which I think has a much punchier harder sound which really suits upfront club music, Techno/House etc
Tempest is a really fun machine to use standalone but there are annoying limitations in its own sequencer, so I use it as a sound module. It has limited MIDI implementation; and only samples built in, but unlike many I like the fact it only has the built in samples - means you have to get creative with available samples and the synthesis options, which are VAST to make something unique.
Bizarre choices made however, such as not outputting the rolls to the MIDI out - which in my use would be great as I use Tempest pads via Cirklon to play itself but unfortunately can’t record the roll MIDI which would’ve made it a great MIDI rhythm controller.
