RE: horton or excalibur
I can only tell you what I did having zero archery experience until a few months ago. I bought an Excalibur Vixen with the factory package. I practiced a little(very little) and I can shoot a sub 2-inch group at 40 yards. I have not modified the bow other than doing a camo job on it. I don't know if other brands are better or more accurate, but this one is good enough for me.
