Am I doing something wrong or is Unity's terrain really garbage?

    I can't get terrain to sculpt worth crap, and I keep looking around for tutorial on it, but all I find are things about the grass and trees and other features. But the terrain's actual geometry just won't sculpt properly, and I can't figure out what's wrong.

    For starters, the smoothing tool, well, it doesn't smooth anything.

    Let's say I have two flat sections and I want to have a gentle slope going between them. I simply can't acheive this. If I try to paint in some terrain betwen the two areas, no matter how carefully I approach the heigher edge, I still get overlap from the brush where it raises the higher section. This wouldn't be so bad if I could actually smooth the geometry afterward, but even with the tool strength pushed up to the maximum I can only slightly round a few rough edges; I have no ability to actually smooth out the shape into anything that looks natural.

    I can try to terrace the area by making a series of strokes with the flatten tool, but these terraces still just don't smooth out into a single slope. I can polish it for five straight minutes and only get the edges rounded, not the actual shape of the geometry. I can use larger brushes and sharper brushes and smaller brushes and softer brushes, but I am constantly left with the same result.
    This is particularly frustrating when compared to the fact that I can't even set the paint to to a strength of "1" without it turning into a freaking firehose.

    What am I doing wrong here? I can't fathom that Unity would actually make a terrain system this broken and still not fix it after three years. Why can't I sculpt my basic geometry?
