Those are to very different APV's one is a VV and the other a Hybrid (rebuildable attie). Also better depends on the user, but as far as new ones that I know of I think the smokteck provari looking stacked battery
mod is coming and it's supposed to pack some serious power something like a 5 amp limit. Also L-Rider (lavatube) has the 1.5 that has been released recently and the new chrome, SS, and copper
buy Apollo (VTube). I think they will be coming out with a version 2.0 that is the 1.5 internals in a the new body style of the chrome/ss/copper lavatube.
