I've had them all, tiller, side console and full windshield and they all have good and bad points depending on what your doing.
Tillers are nice, as long as they have a flat floor, as that makes moving around the boat easy with no obstructions but they offer no protection from lousy wet days.
I had a Crestliner 1650 SC for a long time and the side console was nice as it gave the driver protection from the elements when running around the lake on nasty days but does nothing for the passenger(s). You do have to work around the console but I never found that to be an issue and the bigger the boat the less hassle it will be.
You don't mention full windshield boats so I assume you don't want one but they sure are nice, especially with a fully enclosed top that protects everyone when the weathers is cold and wet and the cold fall winds are howling.
As I said above they all have good points and bad, you just have to pick whet works best for your style of fishing.
