I have the Arctery'x and the Tethrd, currently, and I've had a Chinese pair of Arctery'x knock-offs... I have no gripe or issue with any off them, personally! I wear mine 99% of the time, EXCEPT if I'm layering my legs at the tree. No issues during long/brushy walks in. The Chinese pair had inferior quality elastic etc., but I didn't have them long enough for anything to deteriorate (so no issues other than possible longevity... The EWO pads seem to fit into this category very nicely, with the exception of connection buckle type. I've eyed them up, but no real reason to purchase given the two sets that I have, which are most likely virtually identical in fit and function. Definitely a consideration, if and or when, I need a new pair.
If you can't guess, I like this style...
