No first hand experience, but I've read that a lot of the 2-stage match triggers out there fail in the abusive environment of an "urban rifle" course that requires upwards of 500 rds expended in a couple days' time.
[There's an expensive proposition, ammo-wise, these days.]
One that I recall reportedly not failing was the CMMG version, and I've kicked around getting one... but of course like everything else right now, they appear on terminal backorder.
Other than that, for my own purposes I'm reluctant to change much of the basic milspec arrangement for fear of decrementing what is supposed to be an abuse-tolerant mechanism.
Reliability #1
Durability #2
Accuracy #3
Parts redundancy/availability #4
Just my $0.02, probably worth less than the stick price.
