like Mr.Shookie said, everyone's opinion is likely biased.
so i'm going to be as neutral as possible.
1st thing to do is to look at the parts support, which car gets a pretty comprehensive parts support from your LHS.
I've never had a teamlosi car before but based on recent performance in the worlds level, i'd pick a tamiya or associated
TA05 is quite a performer out of the box, and I believe that a team kit TC4 is as good (or maybe better). I own a TC3 and TA05 and I must say I am satisfied with their performances.
