StreetComplete lets you place trash cans and benches too (among other things) using the "Things" overlay. IMO Every Door has a much more complicated UI, though it's also more of a full featured editor than StreetComplete. (Though still less so than something like Vespucci.)
Is that a new feature? I have over a thousand contributions on StreetComplete (casually using it during walks) and somehow I never noticed that button.
The overlays are intentionally a bit hidden, since they're more of a power-user feature and I appreciate that StreetComplete retains beginner-friendliness as a core tenet. But the overlays are indeed awesome for survey-type walks where you just want to make sure that all sidewalks are mapped correctly, or to see which shops are still missing.
