I think it would be easier to keep air in your mouth if it doesn't have a tube sticking out of it... that's what, 100-150 mL (around 100 for me, and I have a small mouth).

This extra air will not only give you a bit more oxygen for that aspetto, but will also make it easier to equalize.

Also, would you still have it in when you surfaced? If so, you'd have to clear before you could take a breath. If you drop it before/when you surface, then you might as well drop it upon entry.

I don't know about spearfishing, but I've never met a freediver who "leaves it in".

You take it out for safety. If you leave it in your mouth and black out it holds your mouth open and your lungs can potentially fill with water.

Also some divers I've dived with surface with it and immediately go into a face down position it's very hard to tell if they're breathing or blacked out.

At the performance freediving clinic they call diving with a snorkel in your mouth a beer offense. :naughty I committed many :friday mmmm duff
Leave it out definitely!
Safety being the first reason. Adding to what alein and smellsfishy said, if you clear it upon coming to the surface you are increasing your potential for a blackout because it's not the best way to get fresh air back into your lungs/blood/brain. And clearing creates a sudden blood pressure change.

Feeling much more natural underwater being second reason.

Reason number 3 is for spearfishing: when you keep it in your mouth it might keep leaking with bubbles now and then. Not a good way to attract fish.
