Its a bunch of hogwash - crimps fail just as much as one does that is soldered. There is no such thing as a perfect solder job as nor is there the perfect crimp. What protects the connection is the shrink tubing. A few things to consider:

1. crimp is a mechanical connection only.
2. solder is chemical connection if done properly.

Neither of the two work properly without concerns for connectivity and prevention of corrosion.

None of the two account for the type of connections being used. I have said this time and time again - soldering is a great agent for connections and the result is often stronger than the gauge of wire required to connect. Heat shrink connections offer that mechanical buffer that is all. Crimp - solder, do both - the weakest point will still be the quality of connection or quality of the wire. Just that simple. A boats electronics - the wiring doesn't move or get stressed out any more than a car does - seriously. If you have a boat that flexes that much then stop putting electronics ins a West Marine dinghy.

The factor in longevity is preventing corrosion from the latent salt air. Whether you crimp or solder - its the application of covering to prevent intrusion of elements that defines the bond. Just like you can't take a LCD and place in the cockpit - you first have to do some sealing to marinize it...I've seen both suffer death throws... try hard enough you make even the most respected solution fail..
