Thanks for the feedback everybody!! Much, much appreciated

I'm indeed new to MPC, but I'm pretty quick at picking things up.
Improvement in speed is indeed not of huge importance (should have perhaps put it differently in the original post) but workflow is a big factor for me. I've played around with an MPC Live a bit in the past, but I was instantly missing some buttons. The One does seem to resolve that problem (a bit), but the X seems to offer more hands on control at the cost of portability.
Perhaps I should mention that I also have a Cirklon, and will mainly be using the MPC as a sample / beat production system... Cirklon handles my synths.
Thanks for all the feedback so far, love it! I'm leaning a bit more to the MPC One right now, but please do convince me otherwise if you really think so

Ps: The X "offer" is at an official retailer and has 3 year warranty... But if I get the One, which costs €750, it also has the 3 year warranty of course.
