Like CHLChris, I've gone with bottom 1/3 cowitness but can see advantages for absolute cowitness too. If your rear sight flips down then absolute might be the best, maybe not as good with a fixed rear. No wrong answer, preference as you said. People should get familiar with both, it's hard to visualize until you actually compare them.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
You'll remember the quality of a gun long after you forget how much you paid for it.
