Assuming you've narrowed it down to these two boats for reasons of your own; I can say there's no choice. I've seen the Otter and I wouldn't have one. I've had 2 Puddlers for 6 years, beat them up good, they ride side-saddle in the airboat and get chewed up, sit out in the hot Florida sun the rest of the year, paddle nice, and other than being a bit beat up looking, are still going strong. They're one tough boat. I'll likely have a 3rd before season starts. Capt Scott also has 2. He bought them after hunting out of mine. I'm sure the Pintail is just as fine a boat and weights less, and is a much cleaner design. I'm sure it slips through weeds much easier too, not to mention it actually looks like a duck boat rather than some cheap prop from the movie "Transformers".
