That's a very broad question! Best for what purpose?? A solder or a policeman needs a different trigger than a varmit hunter or target shooter. So you cover a lot of territory.. In factory triggers--- I like the Winchester trigger for a hunting trigger for it's simplicity and still being adjustable to a decent hunting pull. It's also nearly immune to fouling and changes caused by crud or congealed oil. The Remington trigger is easily adjustable but as are all enclosed triggers it's easily fouled by dirt and osidized oils. It also has an extra component that makes it more likely to have an AD in the event of a failure.. Most enclosed triggers will simply fail to retain the striker,, the remington can release it when the safety is moved to off so while it's a good trigger it does have a few problems.. Please note that Remington is replacing the trigger in 2007. While I have seen the replacement I have not seen any details, but it most likely will not be as adjustable as the old one.. The Savage AccuTrigger is a really good design but I have not yet really worked with one.. The older savage triggers were either not adjustable or were adjustable but of very poor designs. Most of the adjustable ones used a single rod shaped srping wire to provide both trigger return and sear resett.. a very poor idea. Many other factory triggers are acceptable but most are not as adjustable as the Winchester or they are enclosed designs with their inherent crud collecting problems orr both. The mauser 2 stage is a good trigger if properly adjusted. dafe reliable and can be made acceptably light for hunting purposes. As to after market triggers there are leagion.. Timney is a really good trigger for the money and is noted for it's enclosed designs although they make triggers for rifles such as the savage to increase their utility and adjustability.. Some of the best triggers ever designed(my opinion of course) were used on some of the match grade 22 rifles with the Anschutts and the Winchester 52(C&D) leaaping to mind. The Annies use a multy lever trigger that while fairly complicated is truly a wonder.. The Winchester micromotion trigger is amazing. When correctly adjusted it just seems to fire when you thiink about and yet is safe to handle.. I like set triggers but they do have drawbacks.. the double set variety often or perhaps usually has a poor unset pull and the motion of the hand and the ensueing changes in position can be disturbing.. the single set triggers usually jump away from the finger when they trip. This creates a kind of super excessive over travle situation they is not a good thing. I can work with them but they are not found on rifles used by the elite shooters in the world. They just don't solve more problems than they create. There was a design used by winchester on some rifles called a close coupled set trigger. They were better than the normal 2 trigger settrigger and better than the normal single set. Unfortunately only a very few were made and no one produces anything like them today. For hunting I prefer the Winchester factory trigger. It is reliable, fairly easy to adjust and simple.. In a target setting I'm not really qualified but like a single stage trigger of around 2 pounds with no creep or over travel,.., there are many brands-Shilen comes to mind.. Just my preference at the end there though!!
