In my opinion, all of the bows you have listed are fine bows. It depends on what you are looking for in a bow.
The Stalkers have a good reputation but I have had no personal experience with them. Is it a newer model? If so do a search here and you'll find plenty of feedback.
Fedoras are great bows.....plenty quick and easily quieted down. Grip on mine was a bit large for my tastes, but that is a personal thing.
Hill Country bows are very sweet shooters. One of the best kept secrets so to speak. If the right lefty would come up for sale, I'd own one.
Any Dwyer bow is a keeper. More of a "traditional bow" I guess you'd say. It has a nice grip.
All the bows on your list are made by fine gentlemen and craftsmen. You really can't go wrong with any of them. You didn't mention the bow length, weight@ your draw length on any of the bows or what the length and draw weight is on your current bow. If your current bow feels good(draw weight and bow length) you may want to go with the bow that is close to what you have. You should be able to use the same arrows, or at least mess with the point weight to get them where you need them. With the Stalker or the Hill Country you have the option of purchasing additional limbs (longer, shorter, lighter, heavier).
Do a search here on all of the bows you're looking at. You'll find some info on all them , I'm sure. Then google the bows and hit their websites for some close ups of the grips.
In the end it is all up to you and what you like. Just don't overbow yourself and be sure to have fun.
