RE: best bow of all
pup,
It really isn't easy to just tell you which bow is best in each manufacturer's lineup because most bows are built for specific applications.
Lets take Sag and P12's Merlin for example. I don't think many folks will argue that their Max2000 and Supernova are probably some of the most praised in their lineup. Though I am sure either one could be used effectively as a hunting bow I do believe that they were originally designed as bows to be used for indoor or field target archery.
The opposite is true as well. Take a look at some of the Bowtech lineup. I don't think anyone will argue that their Tech29 and Mighty Mite are excellent bowhunting treestand and ground blind bows that could possibly be used for competitive 3D or target archery. They definitely weren't made for that type of shooting though.
If you could specify the application then maybe we could give you one or two bows from each lineup to consider.
