I enjoy my canoe. It is a 17' Mad River Canoe (you probably guessed by the Confident Rabbit avatar) Duck Hunter. It offered plenty of room for the wife and I, a couple huskies, and plenty of camping gear. We have a couple kids now, so things are a bit tighter, but we still enjoy it for day trips and fishing. Obviously it doesn't hold as much overnight gear with the kids, but we can still do a night or two with the crew.
If it was just me, I think I would still go for a canoe as it carries more gear and a dog comfortably than some of the other options. Canoes can be a bit heavier than kayaks. They also each handle differently. So don't assume one boat is representative of its kin. Definitely try to paddle a few before buying anything.
Good luck in your choice!
