Nope. I find the DCC clips keep the exact ride height of the pistol grip which is invaluable for maintaining a better AIWB index and draw, for me.
Before switching, I had two otherwise identical rigs, one with DCC clips and one with loops. Spent some time evaluating both. No comparison, for me- the clips were clearly better overall.
The loops main advantage is they allow you to move the rig around quite a bit- which, for me, is also their chief disadvantage. Different people have different priorities, builds, and needs, so it’s great we have such solid choices.
