Wilsons are the gold standard. Short of damaging them somehow, they typically won't fail or wear out. There's likely less than 1% of us that shoot so much as to wear the mags out.
I've used Tripp's plenty as well but, they are pricey compared to the Wilsons. People that complain about the cost of a Wilson? Have you ever shopped for a factory Sig magazine as well? Good mags are worth the price most of the time.
The Tripp's are one of the few that I'd say cost more than they should. That said, they also work very well.
I've got a .357sig Nighthawk and found the Tripp mags were the most reliable in that odd caliber/gun combination, so for that one, I had to eat the cost and just buy those.
