This is what you want to use. Or something like it.

No. That is what you want to use and only that. They are so much better than normal plastic wall anchors that it's not even competition.

Maybe not in drywall. I feel like there you would be better with more specialized stuff.

Its a compressive hollow wall anchor. There is nothing exactly special about it. There are many wall anchors with similar or superior performance. I agree that there are wall anchors that are much worse, but that does not mean the a duopower anchor is the only acceptable one to use.

It's really a multi purpose anchor. It'll expand differently, depending on the cavities. It can either just spread in a solid wall or it can bunch up in a cavity.
