Vibby used to be the best, because it allowed annotation, and you could get several clips in one project. But Vibby has closed down.
After trying out a few alternatives, today, I still think Youtube Trimmer is still the best alternative. It's very simple to use. Of course, unlike Vibby, each resulting link contains one clip only. But in most use cases, that is OK.
A reminder: When done, copy the Second link to use.

(of course, Youtube has its built-in clip creator. But you can only get a one-minute clip at most.)
