If you simply want to shoot tight groups from a bench with your match-grade ammo (hunting/varminting included), the ideal triggers are going to be the $150-300 options from Timney, Geiselle, Hyperfire, etc.
If you're chasing the above on a budget, RRA may be an excellent answer. In my experience RRA's match triggers are generally good, but a little inconsistent (lots of travel/drag in some cases).
If you want an upgraded utility (defense/tactical/target/varmint/whatever) trigger, I'd highly recommend the ALG QMS triggers. They're mildly heavy, but crisp and clean. You'll only have to spend about $50. And they're about as close to mil-spec bomb-proof reliability as anyone could ask for. Many of the higher end $200-ish triggers have been known to break down at very inopportune moments.
