They're both really high quality goggles. Both have very high optical quality and good peripheral vision. The biggest difference is really what fits your face best. The other factor is what fits your helmet best. The wisdoms have plastic pieces that kinda stick out connecting the strap to the goggle frame, and can get in the way on some helmets (fit some helmets fine, and there's also a helmet specific strap you can buy as an accessory).
The best thing to do is go to a store with your helmet if you have one, and try them on, see what fits best. After that, it's just personal taste really. You can't go wrong with either really.
I have two pairs of Wisdoms and I love them, and I had a pair of A frames previously. All great goggles. My only problem with the Wisdoms is that on occasion the plastic connecting piece I mentioned will snag on my hood when I turn my head, but it's just a minor annoyance.
