As Ianwater said it’s all about capacity and power. The larger the better because you will find so many uses for that extra capacity, like effortless sawing of wide veneers, and small logs. Also important, but not often mentioned is the capacity to rip thick planks. So much easier than running those through your table saw. I have an 18" bandsaw and I wouldn’t trade it for anything.
