I've had Losi, Traxxas and Arrrma.
There's a lot of good brands out there these days. I went with Traxxas mainly due to I liked how some of their cars looked and there's dealers in Jupiter, Port St. Lucie and Lake Park that have parts/good CS. And I've had some good luck with their vehicles/batteries in terms of durability and longevity . It's quite hard to break the 10 scale trucks. Unless you are going flat out at the skate park or hit a curb at max speed, they have weak spots intentionally so something like the axle snaps off which is fairly easy to replace.
Arrma has the Senton and Traxxas has the Slash for the offroad looking baja trucks in the 1/10 scale range(pic never loaded for me). Both offer brushed and brushless. Brushless has a higher price tag but is way faster, more instant acceleration and should last way longer. The brushed kits usually come with a battery and charger included in the price for Traxxas, so it is quite cheaper initial cost. Just get 4x4 for which ever brand you buy if you want to use it in grass. More moving parts but 2x4 will struggle in grass. Some of the bigger brands have tons of upgrades/different body styles that are widely available.
I know with the traxxas VXL motors you can put it in training mode(50% power) and the 2s with stock gearing probably taps out at 30mph.
