Can't speak for Athlon, never owned one. The Vantage line are decent scopes for the money and I own at least a dozen between 2-7, 3-9, 4-12x40's and a 4-12x50 AO IR. If you decide on one, get the IR version. Even if you never use the IR part, it still gives you a glass etched reticle instead of the wire one the standard Vantage comes with.
As already mentioned, they aren't recommended for springers over 12 fpe but every one of mine has been used on guns no lower than 14 fpe and I've never had a problem with any of them, maybe in part to most of them also having IR and the etched reticle.
End of random lame 2 cents...lol.
p.s.- I'll also agree with goodoldbvc on the Airmax scopes. Bit more money but magnum springer rated and I'm a fan of the AMX reticle. I own 7.
