I respectfully disagree with most of the above.
Wind knot…. Mono core almost eliminates that.
Snag…. Not too apparent. However, it can cut kelp.
Digging into reel…. If angler pulls hard on reel after the snag. Could happen with mono too.
Backlash…. Ok it is harder to undo backlash than mono, but mono can get backlash too. I have a tool for that.
Wear on the gear…. Perhaps with top guide on the fishing rod.
Having to tie special knot… Not really, I use improved clinch knot all the time with braid. wetting not needed either.
Not being to handle the line…. I give that one, but I have tool for that too!
Etc….?
It has a small diameter than mono, thus more line on the spool. That could be the difference between landing the fish, or getting spooled.
No stretch…. Good to feel the bit, but also could lose fish due to no give.
Fishing for halibut in Alaska in 170-300 feet of water, you want to feel every bite. you want to set the hook with no slack. Not too easy with mono.
It boils down to personal preference and the type of fishing.
