If i have to choose,i would still go for Asus first,then Gigabyte UD4 or MSI GD65,but dont expect those mobos to be bug free - they also have they problems,thing is that Asus selling way more mobos than GB and MSI,thats why more problems,but overall i dont think GB or MSI have better boards.
No point to pay more for expensive mobos also - you get everything you need and more from those,i dont think extra switch worth 40+ quid..Even if you overcklock 200mhz more
Also,i think Asus will fix those issues,its simple that they need time with that new UEFI thing,have same problems in the past with Asus Maximus Formula's,and when they fix they bios,it was rock stable,no problems at all,they probably need few more UEFI versions to fix most problems
