I prefer the regular lanyards. The large are really nice to display pins on, but I think they can be too heavy/cumbersome. To be fair, I am not a huge lanyard person. I use the small Disney pin bag I use like a fanny pack.
I definitely prefer regular lanyards for when I go to the parks. Most of the time I’m only bringing traders and not collection type pins so the smaller lanyards work just fine. If I’m trying to show off some of my larger pins or maybe wear a themed lanyard for the day I’ll use a custom wide lanyard for those situations.
