Odd. No Tyan in the list?
Anyways, voted for Intel. Out of a hundred Intel boards, I've only seen a couple go bad. Whichever sloppy one that ran SDRAM through a memory translator hub...one of the i820s if I remember correctly...
Would probably place Gigabyte and Asus tied for second after Intel.
Then probably Supermicro and the rest in no determined order yet.
