I've been told the factory triggers on the stainless steel Remingtons are much better than the triggers on the non-stainless steel models.
Since my Rem700s are all SS I can't comment on the others.
There are several web sites which very clearly state how to adjust the factory Remington triggers.
I think it really depends on how light of a pull you need.
The Jewel will surely be better, but if all you need is a 2 to 2 1/2 pound pull the factory SS triggers are pretty good.
