i really liked my xt8, i had some parts break that just didnt seem right , but it was when it was around 30* so that may be the cause , parts availability can be tough unless your lhs carries xray , amain is a great place for it online, if you dont mind ordering parts i say get the xt8
never owning a losi i can only lean towards what i know , but.......... the losi would be new and may be cheaper in the long run and its always nice to have a clean slate..
