I like the EVGA for the 3 bios's, 2 esata ports and the board has a sweeter look to it over the asus board.
Here's what your looking at price wise for both boards..
Newegg.ca - EVGA P55 FTW SLI 132-LF-E657-KR LGA1156 Intel P55 ATX Intel Motherboard $240, $200 after $40 MIR
Newegg.ca - ASUS P7P55D Deluxe LGA 1156 Intel P55 ATX Intel Motherboard $220
