I'll follow up with the results.

OSD. One of them is the number of PGs stored on that OSD.
did you benchmark the both to compare for any bigger runtime difference?
E.g., some loop with a few thousands rados mon_command calls in perl for each
using HiRes timer to measure total loop time and compare?
I'd not care for a few percent, but would be good to know if this is

check to not do so IMO.
