I have a Outcast Discovery 9ir and I like it but its the only one I've used. When I bought mine I phoned Outcast and talked to them about their pontoon boats. Boats like the cougar, panther or any of the ones that sit really low in the water are more for still waters. The 9ir has more rocker and is better for flowing water. So it depends where you are going to do most of your fishing but both styles will work in flowing and still waters.
