I only wear my snorkel when working with students.
Otherwise, my snorkel stays in the dive bag. I had one operator "require" you do take a snorkel with you on the dive, so I pulled mine out of the bag, and used zip-ties to secure it to my rig.
On one dive, it was really sloppy on the surface, and it would have been easier to have a snorkel, but you can use the regulator as a splash guard and breathe around it without using any air from your tank and keep the water out of your mouth (or just use the air from your tank).
