u2q7 has the better diff for track, m2b4 for draging.

the ratio's on the m2b4 are better imo as there is less of a drop between 2nd and 3rd

Click on the wiki lude tab at the top, there is a gear ratio calculator which will show you the max speed per gear and vtec cross over with each box for your wheel size. It's the one I made ;)

u2q7 early gearbox has 5th gear crunch as a common issue also.
