For anyone who's interested, I found a fairly recent review comparing the 2 (Boxwave Crystal vs Anti-Glare).

It's not *that* detailed, but in the end, the review chooses the Crystal Boxwave due to its clarity.
I'm trying to see if the Crystal also repels dust and fingerprints like the Anti-Glare does, however, but I doubt it's as effective in this regard.
