I am going to vote neither. I actually would go with a Vamo V2. Both of my Vamo V3 have had 510
thread issues. The Tesla looks cool but that's all it has going for it. The SVD is a small step up from both of them. A step up from the SVD would be a Zmax Smoktech or Segelei. A step up from the Zmax would be a Provari. It is all a matter of what you want to spend.
