TR909 for the sounds.
TR909 samples from Samples From Mars loaded into the Digitakt is the ideal for me.
TR8S emulation of TR909 if I didn’t own a Digitakt.
I own both a TR8S and a Digitakt and have worked out that Digitakt with quality samples of Roland drum machines is the way to go, for me at least. More flexibility, far better sequencer, one quarter of the footprint (TR8S is awkwardly large in my tiny setup).
