I set, most of the time. It's a habit I got into on the jewelery bench. There are times though that standing is the only way to go. I build on a very stout old PC desk, so it is lower than a counter top and more friendly to setting. I am in the process of building a 3x8 bench for some large kits I have and I expect I'm going to have to find a stool for working on them.

Bad knees and old age also contribuite to this conversation.
