I own an Intel DP67DE board, and what I notice is less features (e.g. # of USB ports, overclocking) than the Gigabyte and ASUS boards I had in the same price bracket. In addition, the board's BIOS seems to have gone through the same growing pains as its Cougar Point chipset - it took 3 revisions before I could dial in any sort of overclocking.
What it does have works reasonably well - the BIOS loads up faster than any other board I've used, fan profiles for the CPU and two case fans are customizable, and I note that it's a bit more power efficient than the Gigabyte P67 UD3P board I used to have.
Note however that I am comparing across generations (my Intel is a P67, the low-end ASUS I had was an AMD 600 series chipset, and the low-end GB was an AMD 770 series).
As for the all-important "Would I buy again?" - yes but not for my main gaming rig

With the exception of the "enthusiast" boards with the skull silkscreened on to the PCB, overclocking is an "extra" for Intel boards, so don't expect it to work.
