Percy Jones was (and still is) way more interesting than Jaco Pastorius, but he was British, not American, so not selfish and not playing louder than the other members of the band. He also had nothing to prove to anybody as Brand X had enough notoriety for their members.
That said, I like Weather Report when the 'Phons was on bass, ahead of his time in his approach, but without that “hey look, that's me playing“ bad habit of Jaco Pastorius.
I'm a fretless player, but my main influences are Percy Jones and Mick Karn, and I'm proud of it.
