Maybe a strange question. I'm reading up on how to build walls from different materials, etc., to get a bit more knowledge. No project in progress, but I simply feel the need to know more.
Something that hasn't quite stuck yet is when to use different types of outer (and also inner) corners. For example, tapetrim, nocoat, aquabead, and all those out there. I initially thought it was much about reinforcing the actual wall "structure." But it's really more about making the corners more resistant to impacts, right?
Can someone walk me through this in a pedagogical way? I've been watching videos on installing outer corners and have read about them—but not exactly when they should and shouldn't be used.
Merry Christmas!

Then you must have a rule in the corner anyway, so these types of moldings are just to reinforce the drywall against attacks from, for example, children, wives, animals, etc., who don't have a sense of how much a drywall can withstand. (It absolutely has nothing to do with clumsy men bumping into corners with boards, tables, etc.) 
Normally, you frame and then attach drywall or OSB/plywood/sawn board and then drywall to the frame. At the outer corners, suitable reinforcement depending on the type of damage you expect. In the garage, I used a metal trim; in the house, self-adhesive plastic moldings with a thin metal sheet. If it's a place that isn't at risk of damage or movement, you can just fill it.
After the moldings, fill and sand. Finally, paint/wallpaper.

A bit along the lines of what I was thinking. So generally speaking, you might say outer corners are used more in public environments and spaces that (as mentioned) are at risk of getting more bumps. And they are therefore never really needed indoors in a regular residence... Sort of.

Normally, you frame and then on the frame you put drywall or OSB/plywood/boarding and then drywall again. In the outer corners, suitable reinforcement depending on the type of damage you anticipate. In the garage, I put a metal edge, in the house self-adhesive plastic strips with a thin sheet of metal. If it's a place that doesn't risk being damaged or moved, you can just fill.
After the strips, fill and sand. Finally, paint/wallpaper.
