Best out of box: Triumph bone collector. I shot mine for the first time the other day and previously helped get my buddy sighted in with his regular triumph and both were better out of the box than I currently shoot my genesis.
Worst: Not sure if I can say I have a worst. I have had a CVA wolf, sighted in a Kodiak Pro for dad, sighted in a Omega with a scope/thumbhole stock for someone who said he couldn't hit the paper, have a genesis and a triumph...and if I had to pick a worst...probably the Wolf...just because it took longer to get a group that was good.
Favorite: I am sure my new fav is now the bone collector...but...I have to say the Genesis holds a place in my heart because of all the hunting memories.
