99.9% of my deer hunting has been with a lever gun, and will continue to be.
Hard to pin down a favorite, but, my old '94 in 30-30 is a go to, dependable performer for me.
I also use an 1886 in 45-70, a 99 Savage in 308, a BLR in 308, and a couple of vintage 1894 30-30's.
Just to bug Rick, I'm working on an 1892 in 44-40 for this year.
It's a cobled together gun, and full of bugs, but I'm getting there.
