Former Maschine user here. I now own the X. I can tell you this (my opinion of course):
Maschine is great. From a controller point of view it is vastly superior in flexibility, workflow, stability. The kits are amazing. Now, there is no standalone with Maschine and really wanted to try out an OTB workflow, because with maschine i was often distracted by the possibilities and doing a lot with the mouse (especially grid editing). And it's so close to a daw like ableton that it frustrated me that actually isn't. The transition from a maschine project into a ableton project (to finish the composition) is so cumbersome that i stopped using it and went with Push2 instead. I reckoned if i'm using the mouse all the time, why not do that in the program all my compositions end up in after all. Ableton.
Now with the MPC X there are a lot of limitations, mostly because it is based on an ancient workflow. And this... is kind of growing on me. The whole psychology behind standalone, not being able to do anything with the PC, is liberating and really helps me focus and get in the flow. I am learning to work with it's limitations and frustrating. It's far from perfect but there are quite a few nifty features unique to the mpc workflow. It really lends itself to sampling, sample manipulation, pitching, copying samples across the pads and making variations. Stuff i didn't do with Maschine. With maschine i would mostly use factory content and build grooves from that.
If you mainly use it in the studio i would strongly recommend the X. The Live has a crippled interface to me, since much needs to be done via the touch screen, which kind of takes away the idea of working on a dedicated machine (with dedicated controls). If you're playing live, that's a different question. If i go live i prefer the push/laptop combi since the live is too limited and would always need to be accompanied by other gear (quality reverb, distortion, master fx, limiter/compressor). But there's no denying the fun of making music on the go with the Live.
So Yes you should give i another try, but first read the manual (or bible as suggested above (..hmmm that sounds devine.

)), watch movies and then take a few hours in the shop. It took me a few weeks to decide wether it fits my workflow. And I don't have the definite answer yet, but i'm having a great time using with the occasional frustration about bugs and some obvious missing features and the occasional double triggering pads. But the limitations work for me and i'm getting faster at doing what i want and, most important, having fun doing so. So yes for me it is a motivator.
But only buy it if you really go standalone. In controller mode it's fine (and more suited to use without the mouse then maschine) but way behind the machine software. E.g. building songs is cumbersome, re ordering sequences and tracks is impossible

.In standalone i can accept those limitations and there are ways around this , but you really need to put in the effort to learn the MPC way. And like with everything, once you learn to master it, you can make great things with anything. I really hope you can try it with someone near you. If i was, you would have been invited, but there are a few thousand miles between us

. Why not buy it, use it for a week or two, and bring it back if it's not you thing. That's possible with GC right?
Good luck!
oh and the MPCX hardware is Ace. That really adds to the users experience imo.
