Is there a huge difference between the work culture, workload (including clinical and admin work), salary, and patient demographics of different polyclinics of different clusters? (E.g nup vs nhgp vs shp)

Current a mmed FP, thinking of changing cluster as I am moving house to the east (currently living in west) in a few months (after marriage). I am actually quite comfortable with my current ops and bosses (worked there for 3+ years, through the COVID pandemic), just that location will be really far (slightly more than 1hr by public transport) after I move house. (And if I do move to shp, it will be a completely different IT system)

Not sure if it is worth it to move, and if other clusters will accept FP who are not trained in their clusters..
