IPG v5 is better unless you don't care about having more tensioning options. Also don't go for the v2 or the xs, they both have plastic cores that could easily break. My cube's metal screw broke, imagine if it had been made out of plastic.
i dont think you can say xs is garbage considering the fact that the majority of top cubers use it and the world record was set on it also j perm thinks its the best cube
