Personally, I would say yes... Because I do own a couple of 3.5-18x scopes (not the XTR-III), but I DO have an XTR-III 5.5-30x56 SCR2 (same scope I posted a link to above). It is a hell of a lot of scope for the money. I've had it on 2 different rifle. I had it on my 16" 6mm ARC bolt gun, and then when I put my thermal on it, I put it on my new Solus (temporarily) until I can figure out what optic I want to run on it full-time.
As to the Vortex comparison, I have not looked through one yet. I bought one several weeks ago through EuroOptic on the premise that it SHOULD only be a few days before it shipped, and It still shows out of stock, but can be backordered... So, I wish I could give you a direct comparison, but unfortunately at this moment, I cannot. BUT, from what I have read here on the forum by people who have, it is similar to (or better than) some Vortex scopes that I have owned and looked through. The pro's who have reviewed them say it's better than the PST-II, which means it has pretty decent glass.
