Had both, personally think some of the big tillers are a little over the top. I ran a 20 foot Alumacraft Comp 190 with a 90hp tiller for a few years. That is about as big as I would want to wrestle with.
If you have young kids in the boat, tillers are nice. Everything stays in front of you. No one falling out without you seeing it happen.
Funny thing, had back and neck problems all those years running a tiller. Switched to side console and those problems went away! For me, a side console is a great river boat. I’m going to be sitting on a bow mount most of the time anyway. That or anchored up. I never saw any advantage to backtrolling on moving water.
Guy needs about 5 boats!!
