Here's my TRUE take on both the MV and Maschine thus far...keeping in mind that I've just only started using Maschine...
The only thing that they really have in common is banging on the pads and applying effects on the fly. Otherwise, they shouldn't even be compared because they do so much more than that. Anyway, here goes my take on whats important...
Ease of use - Maschine
Versatility/Capability - MV
Start up - Maschine
Overall Functionality - MV
Pads - MV
Software - Maschine
Changes on the fly - Maschine
Mobility - MV
Accessibility - Maschine
Commitment/Updates - Maschine
Overall Production - MV
Workflow - Maschine
So there it is in my opinion so far. It's up to you all to decide whats really important to you personally. Maschine gets more of my votes but overall the MV is impeccable because it's a full production piece of gear, from creating - to mixing - to mastering. It put simply...the MV does it all.
