Its the carpenter not the hammer that matters. Get whatever is more comfortable.
The differences between boats seems too small to actually care about. Questions like, is the mamba a split second faster/slower than the deisel seems silly to me when most everything that is being run has been run in t-canyons, crossfires, hurricanes, freefalls, etc.
Boat choice is a personal thing, but personally i think it is best to get a deal on a boat, trash it, get rid of it, get a deal on another boat, repeat until you're 100.
