quick ? on brushless set ups

[cdl822]

Hey guys I was wondering if anyone can help me out I have a wk converted in to a crawler stretched wb, 30 degree axial links in the rear,front and rear axles locked ,axial ax 10 shocks ,hs 645 steering servo mounted over the axle , axial beadlocks weighted with losi rock claws and right now I'm running a moped vr16 esc with a integy 55 t but here is my question I might have a chance to ditch the moped and 55 for a mamba 25 brushless setup with either a cm 2068 motor or a hp-yc 225-5000 so which one would be better for my crawler or are they pretty much equal btw I still have the stock chasis.Thanks for any help.
