Lots of people are staunch supporters of the UQs they have bought or made. It is generally easier to find comments on the pros of a particular make/model/style than the cons.

To help first timers make more educated purchasing decisions what would you do differently next time? What would/did you change about your UQ setup to dial it in? What models/styles didn't quite work for you, and why?

Examples: "I bought a 3/4 Model Y. If I could do it again, I would get an overstuffed full-length Model Z because it is longer, wider, has DWR, and would require less adjustments during the night."
