Pedigrees- Cat vs Pepto vs Rey, etc.

We all know the biggest names but I’m curious what people say about them more than what’s on paper or just physicality. Does anyone have experience with personalities of these famous lines and how they differ? Like within the “cat” line or pepto or rey. I know if I got a horse again it would be AQHA and am curious on what people think are the best **disclaimer I’ve only personally owned an Arabian but have ridden with cutting/versatility trainer, so some exposure to AQHA lines.
