You're comparing apples to oranges.

You need to twist or otherwise adhere wires together before soldering them, e.g. when using heat shrink solder sleeve, unless you've some other way to hold the wires in place.

There's places where you can substitute wago, but often not, e.g. when working with limited space, e.g. repairing a broken wire harness in a car, or similar.

Don't fear! The wago inline splicing connector is here!

I knew about that, actually. It's way too big still for some uses, and I'm guessing won't deal well with anything that repeatedly lightly pulls on the wire (e.g. a trunk hinge). But for some other cases it's great.

Heat shrink solder connectors are the thing to use in this case:

Waterproof, tension proof, will handle more current than the wire itself, hard to install wrong, and very reliable (ie. No fires)
