I am still a newbie. I've only been diving for 9 years and almost 800 dives.
I have a regular snorkel, which I do use for ... snorkeling. And I have a fold-up snorkel, which I never actually carry, much less use.
I have not done a dive with a snorkel since I finished my original OW class. I have also never done a dive where I ended up wishing I had brought a snorkel. I have also never finished a dive, come to the surface, and not had enough gas left in my scuba tank to be able to breathe off my regulator while I swam to my boat or shore exit point, if I wanted to.
