Assuming no experience or any current RC products. I would have to say, The Traxxas TRX4 is going to be a solid platform. Its over built. And if you have a local hobby shop that handles Traxxas, easy parts support. Im not a huge fan of Traxxas but their TRX4 platforms have been pretty solid. Cant say I would recommend their batteries and charger setups, seems expensive, but unless you get adapters for the battery, soldering on new ESC connectors apparently voids the warranty.
After that, Id go for an Axial
Then I would suggest a kit if that is your thing and you are willing to put in some time building and researching instead of open box, charge batteries and go. Vanquish has been pretty good for a solid kit. I have a Gmade Buffalo kit that I have not built yet, but after reviews and watching Youtube videos I am confident it should be fairly solid as well.
I built an Element Gatekeeper kit. I really like the look of the cage design. I really like the shocks. But overall, the performance was just OK. I know a lot of the floppy saurus rex issues are due to the heavy cage. But there is just a little more I had hoped it could do. The pumpkins are kinda large. It is a fantastic rig to hand to someone who has never driven one or a kid that drives hard. No Lexan to worry about getting destroyed and it has been generally tough. I did buy the IFS kit to make it more of a beater/basher trail truck. I do like the Stealth style transmission with overdrive as well. My brother has the Ecto, which I liked a lot, so I got the Gatekeeper kit. His performs way better, again I believe due to the lexan body vs full cage rig sitting on top of standard C channel frame rails.
I also have a Redcat Gen 8 International Scout. Out of the box performance has been again ok, but I have not really spent any time tuning or replacing any parts like heavier wheels, adjusting shocks, changing battery placement. I again treat this one as a loaner beater rig since I got a pair of them on a crazy sale.
Lastly, and only for the sake of something different would be RC4WD and the Trail Finder 2. Its scale, it performs terrible without any help from mods. But it is on Leaf Spring suspension and if you really want a challenge it can fill that role. I would however, consider the Gmade Sawback and research that more if the wheelbase is similar to a 12.3 ish. But I dont think you can get that leaf spring sawback anymore.
You cant really go wrong with a popular branded vehicle. Boils down to. Superior performance? Something like a Capra, or Vanquish kit. Prefer more scale/trail truck that can crawl? Any of the others should suffice. Hardcore scale appearance RC4WD, or heavily adding accessories to any of the others.
Hope the wall of text helps.
