I’d get which ever one you like better. They will all perform differently and they can all be upgraded to perform better.
If your just going to take it on hikes with the kids, get something with larger tires, low cog and one that parts are easy to get, for cheap.
My two younger kids have ax10s, 2.2s make it easy and fun for them to drive. (8yrs and 5yrs)
My oldest has an optic. He loves it. Spends way less time flipped over, so that is a good option.
I only say those things since I’m sure the kids will be driving the rc along with you. Parts are cheap and easy to be had for the optic, stance, axial (idk about the Gilamon yet though) and Traxxas.
