What has been said is pretty much the truth about triggers.
All contender and G-2 barrels will interchange< except the new G-2 Blackpowder. Only works on G-2.
All Encore and Prohunter barrels interchage,.
Encore and Contender(includes G-2) DO NOT interchange.(Whenever I say contender it includes G-2 unles I say something different.
Now some side notes, some of the older barrels will not work on the newer contenders with out changing the locking bolt to the newer style.
not hard to do and they are not expensive from T/C.
The new pro hunter has one thing over the reg Encore I really like, the swing hammer. T/C is very much against a hammer extension on their guns, with the swing hammer you do not need an extension to clear the scope.
Now for which is best, I happen to like all of them, since I have each I guess I should.
If I was going to buy just one and was sure I would not have any more I would do this.
First, I would think about how I was going to use the firearm.
Hunting, if so what, big small, all on ths planet.
Just put holes in paper.
Do you reload or use factory ammo only,
If you reload and like the oddball cartidges?
OK now my opinion, if you want the use cartridge such as 308, 338, 30-06 270, 300 win mag 416 rigby you have to get an Encore.
If a 30-30, 223, 7-30, 444, 357, or any of the others listed in the contender catalog will do for you then a contender is good for you
The encore will shoot any contender cartridge but not vise-a-versa.
There are many more calibers made fore the contender than for the encore by the factory, so your choice of cheaper barrels are greater for the contender then for the encore.
The custom makers will make any caliber you want foer the contender and encore( well at least the calibers that are safe)
Good luck
