You can't go wrong with either one. They are both great choices so pick whichever one you like the most. If I was you, I would chose the Losi 2.0 simply because you aready have the truggy. By having the same buggy and truggy platforms you reduce the amont of partes needed because they share most of the same parts. Also, maintenance will be easier because you are already used to the Losi platform so no learning curve. Now if you just want to Xray that is fine. You will end up with an odd jumble of parts if you don't keep everything organized. Just make sure that you get the new Xray if you get one (the 808 2009 Spec).
