The advantage of a bore pig/gopher is one pass deep fouling control extreme consistency from shot to shot. This also saves precious time during a match that's better used for aiming and doping the wind/mirage. These wipers go in WET (with a trailing dry patch, mostly to dry the chamber) and they do an extremely thorough land/groove cleaning that allows shot-to-shot consistency.
I dunno of anyone, anywhere, doing this consistent a fouling control with just one pass, and why lots, if not most, of the dedicated match shooters use wipers and not just patches.
I'd say, won't know until you give wipers a try and see how they stack up against other fouling control processes and methods. I wasn't all that hep about wipers when they first came out, but after a season of using BACO wiper pigs, that totally changed my mind about 'em, and got even better results with gophers.
But, hey, it's all good, do whatever works best for you, as it should be.
PS - I started off using a Tupperware container for both wet and dry patches, what a pain. A Patch Popper is SO much easier and faster for retrieving patches. Again, a no-fumbling time saver for match shooting.
