My only experience with them has been when dong some H.D. fishing, i.e., steelhead, salmon and with salt water, red drum - and all of this is when fishing from a canoe or boat. The rings allowed me to change lures quicker. Otherwise, when stream fishing or small lakes and ponds (again from the canoe) using one of my 5wt rods, I've found tying on a tippet using a double surgeon's knot and then a clinch knot for the fly, to be just satisfactory.
