Pears are better. Unless they're not fully ripe yet. Like when they're too crisp? Yeah, that sucks.
I'm also not so fond of the mushy mushy type in syrup in cans. Those suck too. I can't even imagine wanting to put that in my mouth.
And can you imagine how gross something like "pearsauce" would be? Applesauce, sure, but not pearsauce. Ewww. ew ew ew.
But pears are definitely better.
