fixd powers
I started with fixed 4x, cause that was the norm, went to 3x9 with everybody else, and now have stated looking at 6x fixed. I've not switched back exclusively to fixed power scopes on hunting rifles (read deer for me) but I have several favorites that wear Leupold 6x36mm and a couple more that wear 2.5x, and do all I've ever needed them to do.
It seemed that I kept my 3x9's on 6x most of the time anyhow. On several occasions, after a shot, long or close, I'd look and the dial was on 6x. At that point I began to think fixed power again.
As far as price goes, the Burris 6x40mm seems an affordable scope. Cheaper than the Leupold 6x36 and 6x42 too. I'm believing tougher than than the various import variables as well.
For me its a parts thing too. Fewer parts just seems to mean less moving parts and more durability, equals less to go wrong.
