I am an admitted Leupold fan but will be objective here. I have numerous Leupolds from VXI (free, wont buy one) to a Mark 4, Weaver Grand Slam 6-20 and K-9 50 mm, and have used the new Redfield.
Just a couple of days ago me and a young man were working up loads for his 300WSM. It is equipped with a Redfield 3x9. I also had my 7mm/08 with a Vari X III 2.5 x8 on it; a $400 scope. No comparison. The clarity with the Leupold is remarkably cleared (crisper) and brighter. But this is a scope that cost twice as much. I have no complaints, at all, with the Weaver's I have. I was actually impressed with both for the price. Seems we just compare every scope to a Leupold so If you can afford it, why not just go for it. Why pay $50 bucks less for your second choice?
It all boils down to use. If I was to want a scope for general use where money was a factor the Redfield will give a workable option. For my primary rifle, I prefer better optics. (Heck, I will spend more on glass than the rifle) If your budget is about $400, the VX-2 3x9 is $299. The VX-2 4-12 is just about $400 or a little less. I would go with the 4-12 and never look back.
JMO. Good Luck.
