I would love to see a ranking of your ukuleles. I'm not mainly a concert player, but your list of ukes includes many that I've liked or am interested in, though also quite a few that I've never tried. I'm guessing you wouldn't have a straight, linear ranking for them, but if you had to put them in an order of preference, I'd be curious what your ranking would be.
You're right that there's a lot of subjectivity involved, but there's enough overlap that other people's opinions can be meaningful points of data. I don't think my opinion trumps anyone else's. But I bet if enough people offered opinions, we'd start to see some broad patterns from which we could derive some conclusions that might fit with own preferences. Maybe enough to make predictions, since we can't all go out and buy everything we're curious about. Anyway, whenever I see these "what's the best X" type of question, I invariably see experienced people demur because of the subjectivity involved. Yet I'm interested in hearing other people's opinions. Especially people who've had more experience. Maybe better just to ask "what's your favorite X?"
I bow to rafter's wisdom and modify my original question to; What's your favorite "X" soprano?
