Wow, this post is missing nopoop, lazs and ripsnort!
WB has a historical slant, AH has a balanced, free for all slant. To each his own.
WB could very well disappear soon, as in weeks or months. (or not) Of course, the death of WB has been predicted for the good part of a decade.
AH will disappear eventually as well.
WB has a decent IJ planeset with a suspect damage model.
AH has no Ki-43 or Ki-84.

(Not a problem for most John Wayne types though.)
WB has buggy, historical maps that cause problems for many people.
AH has non-historical maps designed for playability that many people severly dislike.
WB has lame-prettythang president for the company who couldn't sell 1/2 price gasoline to SUV owners.
AH has an owner who sold his original game to the same lame-prettythang as above.
Both games are not updated frequently enough.
In conclusion: Both games suck in their own special ways. Pick which one you think sucks less or wait (and wait, and wait, and wait) for TR.
zrooster, if you have an exploding suicide truck, then you definitely have an old version of WB. The new, full version is almost 200 megs so I hope you have a fast connection. AH download is much, much smaller, don't know exactly but I'm guessing 30 or 40 megs.
Then again, if you dig the suicide truck, then maybe combat trim and AoA limiting is right for you.
