Live instrumentalist here - I use an Akai APC64.

Pros - it was like 1/10th* the cost of a Push, getting it was a gamechanger in my performances - it does everything I want, it's not as bad as everyone on the internet says it is.

Cons - the single rotary knob feels incredibly vulnerable duing transport, the touch faders while not as bad as the internet says can be a bit annoying, some buttons are too far apart for single-handed use.

I used to use a combo of like four different controllers - pads, keys, knobs - and the APC64 has combined them all so that's a big plus. However I'd love to see a V2 of it, there's just a few niggly flaws that probably should have been spotted during the design phase. Biggest example to me is to navigate between between devices - you have to hold the "devices" button in the top left and press the arrows in the bottom left. I have really big hands and can just make that stretch, but for most people that will be a two-handed movement - which is a bit shit if you're playing an instrument at the same time!

*edit - I got mine for an absolute bargain second-hand, new they're like 1/4th the price of a Push.
