I like the way doomguy put it:
<< I'm an Asus owner but I voted for MSI because they've been releasing solid, reliable, feature filled and low priced motherboards. >>
I have an Asus board (K7M) and have used serveral K7Ms, P5As (and P5ABs), a few P3V4Xs and a pile of P3B-Fs, and I think Asus makes excellent quality boards. But lately MSi has been putting out Asus quality boards with a feature set the size of ABit's, MSi has impressed me alot the last 6 months. I'm not in the motherboard market right now, but if I were I'd be looking at MSi. Asus has been a long time favourite, but I think MSi has displaced them as top spot, though Asus would be a close second, but you don't get two votes.
Oh yeah and MSi's 6 PCI slots standard is nice, it seems most Asus boards are only 5 :frown: Stupid AMR...
