I won't get into the argument either. I've never run a VSpec anyway, so I can't. I can say, of the engines I have run, the R.P Ex Tech is difinitively the best I have personal experience with.
GM- This is a thread for E.T engines, your very first post was totally bagging on them. What's the point of posting in a thread when 1) you have nothing positive to offer? 2) You offer no constructive criticism nor ask any relevant questions about the product? Bottom line, IMO, you're the whiney bratt child looking for attn, and seemingly you have gotten it. Hope you enjoy your moment in the sun here in the E.T engine thread. Now please go away. There is simply NO reason to jump in a thread to be totally negative about the product other than you're begging for attn.
