It all depends on (a) how much you’ve got to spend, and (b) rifle or pistol?
I recommend www.pyramidair.com – they’ve basically got everything, and the staff/users will tell you whats good and what’s not (its almost an Amazon of airguns).
Personally, I really, really want this:

Not simply one of the world’s most accurate air-pistols (you can win an Olympic medal with this puppy)…but an absolute work of art, and an insane bargain. Comparable match-quality pistols could run you 5-10 times as much.
Ahem, sorry for the drooling. As far as rifles go, while I’ve had a ton of fun with my old ten-pumper, you’re really going to want to look at either PCP (pre-chargned pneumatic) or single-cock spring-piston rifles; for one thing, there just aint much choice in multi-pump pneumatics, and for another, they tend to be fairly cheaply-made (no offense, Daisy!).
Beeman has a large following, and I respect their dedication, but I can’t bring myself to believe that they’re not overpricing their stuff a bit. Also, the fact that they don’t update their tech much isn’t really an asset. That said, if you want something that will last a lifetime, these are (they say) tough to beat.
Oh, check out…I believe its the (Sheridan?) Marauder PCP. Supposed to be a good balance of price to performance, if I recall.
