well, ive never driven either the emaxx or the e revo, but if i were your son, i wouldnt mind getting either! the only thing i would probaby worry about is to make sure whatever you're choosing, you choose a model that you can easily find lots of spares and replacements at your lhs or favorite website... not saying either of them are very breakeable, but kids will be kids, and everybody smashes their truck into a tree or something sooner or later...
