I think the arguments that one is better than another is just silly. The best one is the one that YOU PERSONALLY are most comfortable with and that YOU PERSONALLY have the best success with. If you can hit 99/100 with DL but only 80/100 with VL, and I'm the opposite, then it doesn't matter what the statistics and research data say about the average provider. We are not averages!!!
I personally prefer DL, but a lot of people prefer VL and that's ok. First time using VL for me was a disaster. I was a 4th year medical student and my attending wanted me to try it. Never having practiced with it before in any sort of meaningful way (yes, I'd held one and used it on a dummy, but it was more just checking it out than any sort of deliberate practice) it was very disorienting. Anytime I wanted to reposition the blade the entire screen moved and I'd have to re-orient myself. Through some miraculous fluke, I got the tube, but not due to any real skill. I still use VL from time to time, but really just to keep my skills up and so if a medical student or someone training under me is struggling with it and we need a tube quick, I can take over and get it without needing to change equipment.
A large part of it is also just knowing your own limitations. I can use a laryngoscope, take one look at an airway and say to myself, "Well, if I were on dry land I could probably land this, but no way in heck this is happening in the back of a moving medic." and then grab for an LMA instead.
