I drive the RC8T CE and I love it. Since I've never driven a Losi, I can't tell you what, if any, differences there are. What I can tell you is that this is the first truggy that I ever raced (first official race with anything) and it's been something that I've enjoyed growing with. It's been very forgiving as I've learned, and great handling as I've improved my skills.
I believe the factors that you have to look at the closest are, availability, driver support at your track, and your budget.
Good luck! Pick one and drive it like ya stole it!!!!
