All these qualitative results given, rough/loud/slow/hot/black etc don't give you any real quantitative data to make a solid decision on.

I agree with all of that but think, for the majority of DDs, UOA is overkill. If you race (or drive real hard), have FI, &c, UOA can be invaluable. For most DDs that only see occasional "spirited" driving, use a high-quality oil/filter (lots of threads on that), check level (with a quick visual/olfactory/feel check on condition) often, change per manufacturer's recommendations (usually very conservative; if you baby the engine, you can go longer), and enjoy. YMMV
