Both boards have more than enough of what I want in features.
Besides the price difference are there reasons to pick one or the other?
I currently have 1700, 16x2 G.Skill TridentZ 3200 MHz CL14 rams on MSI Tomahawk.
Tomahawk sucks so bad that I am trying to get new board. It doesn't post anything over 2166MHz speed and BIOS update is horrible.

I can get both Taichi and Pro Gaming so I would like to choose one with the LEAST amount of headache. Price difference is negligible.
