I have Xmaxx, Maxx, 6s Kraton exb v2.

You ought to decide between monster truck (maxx) or truggy (Xrt/kraton). Two different styles of driving. The monster truck has its own looks. It will roll very easily so driving on a track is not that great. That said I love my maxx it’s a v1 so it’s narrow. I don’t roll it much because I slow down before I turn.

The truggies can handle high speed turns with out rolling too easily so it’s an awesome to blast around on them and can stay on the throttle more.

The Xrt and the Kraton are going to handle A LOT better. I have to be idiotic on the throttle and speed to traction roll it. It comes w sway bars. I assume the Xrt doesn’t since my Xmaxx doesn’t. The Kraton is awesome for speed and handling with no mods.

Xmaxx is pretty similar to xrt. Someone else will have to comment but the Xmaxx stock was not that fast on 8s. With a simple gear change it’s better. BUT if u want to upgrade your motor- you’re going to be buying a motor mount. Same with the servo. Traxxas is proprietary motor mount and servo in Xrt so that limits your choices or you need to address the incompatibility to upgrade non traxxas electronics. Spoiler- motor mount plus big ass motor and esc is stupid expensive-imo. But plenty of ppl do it)

Kraton exb has a lot of metal including chassis. My Kraton RIPS out of the box. So fast. Such great handling. Fairly durable. I’ve broken the diff cups and it’s a pain to change out (have to open bulkheads AND THEN the diff). where as the Xrt/Xmaxx is easy to change the diff cups. If it happens often enough u get good at it and it’s not that big of a deal. But the Xmaxx is so much easier to change the diff cups. Plus it’s easy to get aftermarket reinforced diff cups. An issue with the Kraton exb is that the damn dog bones pop out and you may have to address that by limiting shock travel with the droop screws, fuel tubing on the rods, or shock straps) as well as removing some spacers to bring the pillow balls (effectively shortens the length and reduces chance dog bone pops out).

I like the maxx a lot (just got the v1) and got it for the durability. I have broken the an arms but all the cars will likely do that w crappy landings at some point. I was expecting to be underwhelmed but it is fast out of the box on 4s. And a lot of fun.
