Insulated terminals for example have absolutely no place in automotive or marine applications, as they're made for fixed wiring installations (i.e. buildings). Open barrel tend to be made for high vibration environments such as automotive applications. And it goes on and on.

That is pretty wide statement.  :)

Not really. Insulated terminals like those in the OP aren't suited for high vibration environments such as automotive applications.  ;D Vibration aside, the complete lack of any seal from the elements also means they're horrible for marine use.

I know they get used a lot for auto use as that's what parts stores carry, but it's not suited for that particular application. They're just cheap and easy.

I have to agree.I've used these in both automotive and marine and they just can't beat proper bare crimps ,solder and heat shrink.I may seem over kill but I always solder the crimped wire as well.More apparent in marine environments is the effect of the coating on the crimp it self and the bare copper wire.Bi metal connections can cause corrosion.So the tinning with solder cooks off the moisture and the heat shrink seals the deal.No more faulty connections.

It is not overkill it is kill, you worsten the connection when soldering a perfectly crimped wire.
The most important rule is to use the correct ferrule and the correct crimptool, after that don't touch it.
Talk to Fraser on this forum, he had some vblogger pull a video on marine cables soldering after the crimp.

TERRA Operative:
Soldering after crimping can cause the wire to fatigue at the point the solder stops as the solder wicks into the cable and forms a hard section of wire with no strain relief at that point.

Also, regarding the fully insulated 'fast-on' style and ring/fork type crimp terminals, I used to use them all day at work in industrial machinery and never had a problem.
We did use name brand crimps with decent quality crimpers though, no dollar store or ebay crap.
