my 2016 2500 was coil, and my 2018 3500 is leaf.. Besides the obvious difference between one ton and 3/4 ton, the coils certainly did ride good, and I felt hauled well within their capabilities. On the cummins forum people say where the coils lack is lateral stability. SO if someone has a tall slide in camper or other "tall heavy load" ( tall can vary depending on peoples opinion I suppose) folks have a noticeable decrease in stability compared to the leaf spring setup. Everything is a trade off I suppose.
