MPC 4000 Plus OR Roland MV 8000???

Im looking for the right machine to go along with my project studio. Ive done some research in the mv 8000 and i just joined the mpc forum, finding out a whole lot more capabilities of the mpc 4k which put a big smile on my face. If anyone could help me out as to which unit to best go with for hip hop i would greatly appreciated. Please state the MAIN differences and why one would be better than the other. Thanks!

Triton Studio 88k
Digi 002 Rack
mics
guitars
bass
etc.
