Choice and Help needed

Hello,

I bought an Amewi MEW4 for my son for Christmas, and he’s having a great time with it. However, I’ve realized that I’m getting into the RC hobby much more than I expected, and we keep fighting who will drive.

Now I’m looking to buy either the Omni Terminator (Carbon Version) or the MJX Hyper GO 10210 (I know it’s not out yet, but I’m considering a pre-order). What would you suggest? We usually drive on gravel, asphalt, and grass.
