In my opinion traxxas models are great for durability, speed, and maintenance with plenty of replacement and hop up parts. I love aarma too, but they just aren’t as easy to work on as traxxas. Check out the traxxas rustler 4x4. As far as price, anything under $350 is not going to have many of the attributes I just mentioned.
Also, working on them is half the fun, esp w a kid since they are just like little cars as far as drivetrain and steering.
