I'll Put ASUS and Gigabyte as equal, but in other case of "tight budget", ECS also serve a good performance as well as fewer features and somewhat worse on QC. In my motherboard list, depending on features/performance, i can say MSI board is the best performance/feature as they had enough or maybe alot of useless thingy on their official software. But when moving on price/performance, ASRock and probably Biostar is the best choice, because i think most of their board are targeted for low end PC build consumer as sometimes, not anybody can buy a High-End and cost alot of of money like ASUS ROG board, EVGA or even MSI gaming series motherboard. Considering how much your budget is, and how much performance you need is very complicated and not as simple as you think. Also, Gigabyte has the best consumer service of all time i've ever seen (above MSI services), instead of performance, in case of Broken or request of RMA, this is might be the important thing to know.
So i put Motherboard brand list depending on how much you can get from your budget as #1 is Gigabyte #2 is ASUS #3 is MSI #4 is ASRock #5 is EVGA #6 is Biostar and ECS #7 is Intel #8 is Gateway and the rest is on the same tier like Jetway, IBM, Foxconn e.t.c.
