e-revo or e-maxx 3905

I've ever convert a 3.3 into brushless and i don't want to remake it another time.
I want a stock machine that i'll only remove the stock electric and put my Neu motor, MGM and my li-po.

Don't want to invest lot of money, this one will stay stock except for the brushless system.

Just want to know wich one have the better tranny and better diffs.

And as i can see the e-maxx have .8MOD gear, and all my gear that i have yet is MOD1.
