Both having reached top 10 in World and Olympic competitions is indicative that they are world class skaters though Weir may be slightly ahead if I were to measure their success with actual placings in Worlds and Olympics. Career wise? .... Well, Jeremy is still an amateur so one cannot tell whether he will have a more or less 'successful' career than Weir. Looks like Weir is heading towards celebrity and show skating where Jeremy has shown a lot of promise in choreographing. Interesting talented young men.
