Ocun harness leg loops-what is the difference between "D" vs. "Y" shapes

I have the Ocun neon lady 3 and am a huge fan of it for comfort, rise, and durability but am looking at getting one of their trad-oriented harnesses so I can get some more hanging belay comfort for multis and have 5 gear loops (probably the twist tech ECO lady because of waist size). In looking at these I notice the neon lady 3 and the weebee models are noted to have "D" shaped leg loops but the twist tech has "Y" shaped leg loops. I understand that it is denoting how the leg loops are attached to the belay loop/ how they split off of the webbing that comes from the belay loop, but what does this mean in terms of comfort/ fit? 

This is important to me because I get pinching and bruising on my inner thighs from a lot of other harness models and the Ocun neon lady 3 was the first harness that didn't cause that (also the petzl luna but when I had to size down the rise was way too short and the belay loops were tiny), if the Y shaped leg loops are different from the D shape I want to know. As a note, I am in the eastern U.S. and haven't seen Ocun in any retail stores I've been in.
