Because they jam, and don't fit in pockets, more expensive, more parts to break, etc.

I've come to hate jump/gap reels and only use spools for those, even if it's a long jump and a PITA to wind back up. I carry one spool on hip d-ring, or on stage strap if carrying extra tanks. I've never had a spool come loose, but if I'm concerned about that on a particular dive there are ways to address that issue.
That's not how I attach bolt snaps to my spool... I put line through one of the holes and then attach bolt snap to the loop that sticks through the hole.
