Interesting, if stereotypical assessment of boat ownership. I would poisit though, that the main reason most new owners end up in a high-volume brand has more to do with price, than knowledge. Not everyone can afford a Morris or Swan, or even a Sabre or Tartan, but they can get a Hunter or Catalina, and that gets them in a boat.
The main thing is to identify what type of sailing you'll be doing, and what you need to be comfortable, and buy accordingly. You don't need a Valiant, if all you're going to do is gunkhole, and you wouldn't buy a coastal cruiser if you intended to circumnavigate. Only you can determine how you'll use the boat, and what works for you. AND, what you can afford. One thing that is true though, most any boat will take more than the captain can, or they wouldn't be afloat.
