Manu, I'll just give you my opinion on the Asrock board because I own it. It works well for me never an issue. I have my 2500k Oced on Air to 4.7 on it 24/7 and maxed out at 5.3 @ 1.48 v. I find the bios fairly easy to navigate through, though I don't like the following. I don't like I can only save 3 BIOS profiles, I'm spoiled by the CHV I have and the 8 profiles. I also don't like how the motherboard controls the fan speed, clearly that's not a big issue, but it buggs me a bit.
