Personally... each has its' own time and place. My typical applications:
Clear mono for smaller, floating, suspending, and shallow running lures... Original Rapalas, X-Raps, walk-the-dog topwaters, buzzbaits, lighter spinnerbaits, etc.
Clear fluoro for sinking lures or deeper presentations... heavier jigs/craw trailers, deep diving cranks, Texas & Carolina rigged soft plastics, etc.
Braid for the heavy slop and weeds... Frogs, jigs, weedless spoons, etc.
