Gander Mountain is pretty "meh" if you ask me. Their gun & fishing prices are pretty high, but 3/4 of the store is usually dedicated to clothing.
Now sure I'm a little biased (much more on fishing), but Bass Pro is even worse. Gander tends to be a little more competitive in firearms prices than Bass Pro. I actually hated that the Huntsville Gander got rid of its on-site gunsmith. Gander sells used firearms.. another plus.
Bass Pro is much less on tackle hocking its own store brand shit & run of the mill stuff, and focusing more on total caricature of southern life shit. It's garbage that I can't walk in there and find a Lew's reel or night fishing lights, much less newer tackle items.. yet I can get camo headrests for a truck and fudge. WTF...
I wish they'd build a Cabela's up here, but there is decent fishing near Eufalua/George Reservoir down in Dothan. To me.. for pricing, broad spectrum of tackle available, etc.. Academy is good. I use tacklewarehouse.com and Cabelas.com a lot though if I'm actually looking for something hunting/fishing wise. To mirror another comment though, for guns? Gander>Academy (both tend to throw some competitive sales though here and there). I will say though.. ammo, Academy seems to be a smidge cheaper.
