I have both. If you go VX 6 you may well need the warranty. Mine dosen't dial in line with verticle post in the reticle, its not overly bad and Ill keep it at this stage but I know of 2 others with a similar problem only worse . Personally in that price range I prefer the Z5 if you can live with the 13 moa travel on the BT.
I find the march better in just about every aspect but might not be worth the extra money to some buyers.
