T4 will be an awesome truck for bashing or racing. The losi also would be. The losi you can get rtr with a brushless in it but I'm not sure of the cost difference. I recommend brushless to anybody and everybody if it will fit in your budget. If not either truck with brushed motors will be excellent for what you want to do and also if you decide to race. The regular losi rtr should have a nicer radio than the t4 comes with. I'm an associated guy so that's the truck I recommend : )~ But looking at all the options out there is a good idea.
Ok here's a link. I guess it's quite a bit extra for the nice radio and brushless:

Here's the regular losi rtr
