I have a 1960 that I'm very happy with. I use it in Lake P and the Dulac / Cocodrie area and its does well both in the marsh and out at the islands. If you're doing a lot of freshwater fishing in enclosed bayous, a smaller boat can be easier to handle but at the (obvious) tradeoff of roominess. My 1960 comfortably fishes 3 people and can fish 4 if everyone knows what they're doing.
As far as other qualities, such as rough water handling, draft, and general build quality, I've been very satisfied. I have a Yamaha F115 on it (the boat is rated for up to 150) and I cruise at 3800-4000RPM at 29-31MPH. At that speed, I typically get 4-5MPG with 2 or 3 people on board, a full load of gear, and at least a half tank of gas.
