Those are good ones, My Matco guy sells them..but I know there are a bunch of other good suppliers...some you can use a small butane torch to do the entire operation, they are presoldered, you heat solder and shrink the insulation all in one step.., they are $$$....

I use a dimpled crimp connector on interior wiring, and sometimes shrink tube over it, depending on what it is and solder and shrinktube on exterior stuff. Some crimp end connectors such as stud eyelets and spades for headlights get lightly crimped, then soldered. No inline butt connectors if I can help it, use a continous wire from terminal to terminal. Pull test each one.

Using the proper tool for the crimp is very important.
