Basically, the grass isn't greener on the other side.
There are just as many people switching to Gigabyte as switching to Asus. The freeze at idle was driving asus users crazy, and I only saw one GB user who was freezing at idle at stock, and we were trying to troubleshoot it.

Another asus B3 user just had the first PCIE slot completely die, after a few days of use. Asus DID fix the cold boot problems MUCH sooner than GB, though. Although I'm happy with the progress GB has made; I flashed f3c on my B3 UD5, used the clear cmos button after power off, and the board didn't even double post at all. I was quite impressed. It does shut off after certain bios option changes, but I think all the boards do that.

I will say that the boot looping on the GB boards was the most annoying issue ever. That probably drove more people away than the asus idle BSOD's.

If someone gets a defective board, jumping ship may or may not help.
