Can I ask from senior gps/fps who have left the system, is it generally better to be an anchor or floater/locum?

I enquired with a chain group (quite a large gp group) and was offered a floater role. Floater means you cover any clinic (throughout Singapore) that needs man power for the day (e.g if the anchor takes mc). Essentially it sounds like a full time employed locum. Pay is similar to an anchor (not too bad la 200-220k/year depending on bonus). I am not sure if I should take it (I presume floater comes with less responsibility and kpi compared to anchor?)
