I still prefer the ASUS P6T Deluxe V2 because of the quality onboard audio. Newer motherboards have added 3rd party SATA 3 6Gbps support as well as 3rd party USB 3 controllers which I don't currently consider necessary.
Only other board I would consider is the ASUS Rampage ][ Extreme which is just the ROG version of the aforemention board.
