Reply to My first Hardware synth

Novation Mininova (~$500) vs Akai Miniak (~$275 used)

I barely know anything about synths, and I don't have too much room for like a 49 key synth.
I know the key's on the Mininova are "mini" but I don't play piano, so i dont feel a real difference.

I can find an UltraNova for $500 used.. any reason I should just "make the synth fit" into my studio?? Should I just skip both and get the UltraNova for some huge reason?

I wanna make sounds like Gesaffelstein and Valentino Khan; I would prefer hardware vs software bc I like having physical knobs to turn.
