Yeah, in my experience, "no engineering" is the most abundant; everything is thrown together willy-nilly to code as fast as possible. I have come across very few real cases of over engineering.

Part of my point is that you don't feel over-engineering nearly as much. If it is under-engineered, it probably doesn't work, and at least has a list of pain points that are fairly obvious.

Over-engineered components will work (sometimes flawlessly), so you don't realize you've spent too much time and money on something until long after you built it.
