Haven’t read thread but look for a drum machine that matches what flavor you want. I would personally suggest the Digitakt.
I think the big thing with the Rytm vs Digitakt thing is that the Digitakt has better sample capabilities while the Rytm obviously has analog drum engines and you can blend the samples with those engines. Also people swear by the sound of the samples going through the analog components.
Some other things to look at:
Erica Synths LXR-02
Twisted Electrons Blast Beats
Isla Instruments S2400 (it’s a sampler with lots of character but it’s large as fuck and almost 15 pounds so I don’t recommend for live use).
You could also look at a DFAM or something and just make your own drum sounds and sample them into the Octatrack. The OT is way more than capable at being a great drum machine
