I've used both and am presently back on a mono kick....simply because it does what I want it to do.....for now.
I also have reels spooled with braid for when I want a different feel....for a while.
Braid has more "sensitivities" than mono....freezing weather was mentioned, as was abrasion (although that seems to be more a factor of fishing around sharp rocks....not found everywhere), there is also "tip wrap" especially in windy conditions that is a pain and could result in a broken off rod tip, and you have never experienced a back-lash until you do with braid....lovely stuff (carry a small tool to fish out the braid....you'll need it), braid has zero memory, zero...which sounds good, but can make some simple operations with mono a pain with braid. Braid, IMO, is excellent for limber, "noodle type" rods, and no good whatsoever for rods with backbone and a fast tip as the strikes and fight can be jolting and snap light leaders (no stretch means NO stretch).
Braid is the ideal flossing line....salt water jig line....float line magnifico...long casting, high current..perfect.
But I do love my mono, too.
