I have and have used many brands over the years and by far the Snap-On pliers are the best for larger or heavier rings. For rings smaller than maybe 1 1/2" OD my set of Milbar interchangeables has held-up for over 20 years - have never ruined a tip with them yet. The Matcos are fair, as are Mac, and KD has both fairly good and poor pliers. As noted already, proper tip size is the main factor for even the high quality pliers to work as expected.
