The thinner sights are FAR more accurate for me. I just sidelined a pistol with Trij HD XR (.122 front width) for inability to shoot a B-8 well at 25 yds. The plain Defoor sights are much better (for me) than the HD. The all black Heinie sight is a close second to the Defoor. Additionally, as others have said, the corners of the HD are really hard on clothing and skin. As you mentioned, sights are a subjective matter and what may work for me may not for others.
