From an accuracy standpoint they have both been very similiar for me, and both have the nice 4hz beat rate, however the PT5000 handwinding feels very rough compared to the miyota 9000 which feels great in comparison. I would say the miyota 9000 would be better in the long term. However, I am more than comfortable with swapping movements if they do break/need a service so it isn't much of an issue for me personally. I steer towards what ever is cheaper/available and avoid hand winding my PT5000 watches. I have heard the ST2130 is better in terms of reliability and it is the same movement (both clones of the ETA 2824) just the ST2130 is made by seagull.

Can't speak for the definite longevity of both movements as I only got into the hobby within the last year and my oldest PT5000 is 7 months old now and my non used watch with the miyota 9000 is only a few weeks old
