Your question is too vague. Also pricing is location specific.
For the USA
ATX, OCing: Probably the Gigabyte Z87X-UD3H (normal OCing) or Z87X-OC (LN2 OCing) , they're both better than the GD65 Gaming and Hero at similar pricepoints
ATX , audiophile: ASUS Maximus VI Hero
MicroATX: Probably the ASUS Maximus VI Gene / Gigabyte G1 Sniper M5 , the AsRock Z87M OC Formula is pricier and has less capable power delivery
