My son borrowed my SWFA with no strategy for its return. I bought another for myself. It’s a great little scope for weight-clarity-durability. The little scope sure can take a beating.
My older Leupold VX-III 2.5-8 is fairly comparable but with more eye relief and a better eye box. I don’t feel the glass is any better then the SWFA. It seems the newest ones are a little dubious as to reliability.
I really like my Trijicon Accupoint 3-9. The small weight penalty is totally worth it. It’s probably the best in its class overall. No complaints whatsoever.
My Swarovski Z3 3-9 has the best glass hands down but just recently the mechanics failed to it's going to a new home as soon as it comes back from Swarovski. It has never been on anything but my nice .270 that I stand hunt with, so it hasn’t had a rough life.
I had a Leica ER 2.5–10 x42 for a brief time. My friend has had it for seven years now on his 375 H&H. Three trips to Africa and several hundred rounds through the rifle with zero issues.
That’s about all I know on the subject.
