all you need to do is find the board with the specs you want, and maybe color, lol
both manufacturers are taiwan based, which translates to a trusty 85% chance they fabricated top quality products...no joke (though of course, some may offer their opine otherwise)
I had an asrock for my last motherboard for an amd 939 socket. It was a pretty good budget board, had quite a few features that others had that were much more expensive. I had a little trouble with the onboard audio but otherwise it was a pretty solid board. I remember foxconn being recommended on other forums a few years ago quite a bit, but i havent heard much of them recently.
