that's all opinion, I don't think it's overrated at all, I think it's the illest product out right now.
but that's just me, and how I work. For some it's dope for others it's not, just like any other piece of gear. Some think the mpc is overrated compared to cubase or logic, again, that's how they work.
I just don't think comparing maschine to a hardware and asking which is better is proper, because they both do things the other one can't.
You can't rock maschine without the computer, period. That's where the comparisons should end
now in terms of workflow and features, maybe you can try...but software will always have access to more power than hardware. It's based on your computer so you get more sounds, space, and memory out the box.
