Tough call there. I don’t own any of the 3s arrmas. They seem really tough, plugand play but they are 90% plastic. This truggy when on sale for $250 (215 with the coupon) you have a tunable 3 diff all metal drive train, aluminum chassis, shock towers, and shocks and will run 4s with a 100amp esc. That is hard to beat. At least one guy switch out the esc for the BLX185 (like 45 bucks on eBay) and runs 6s with the stock motor. I switch out the whole system with the arrma 6s motor and esc.
It will run just fine with the system that comes with it. I geared mine up a bit maybe 16t I think for bashing with no trouble. Comes with 12t installed and a 14t in the box. You will want to at least put the 14t.
Read up on the Granite, lots of good reading and watching. Some cool upgrades available. My pick out of the 3s line would be the typhon because of the 17mm wheel hexes.
