Will anything else suit my needs like a Nucanoe Unlimited?

I’m looking for a pair of kayaks that will fit me, my wife, and 2 boys (3 & 5 years old). The obvious choice is the nucanoe with the optional tandem or buddy seat but I’m just wondering if I’ve missed any other options in this category that would fit the bill? There are a ton of other great kayaks I’ve looked at but none seem to offer the versatility in this regard.
