Ps5 pro 9.60

Hey guys im thinking of pushing the trigger about this.

I found a ps5 pro new sealed unused that the seller says that it has 9.60 firmware.

I checked the firmware around indeed it should be 9.05 to 9.60.

Should i go with it?

Is the jb any stable on these firmwares?

Also is it the same situation with the ps4?

I have a pro on 9.00 which was 8.xx something before and the community in the ps4 reddit was telling me to go to 9.00.

I mean is it possible to do this from i dont k ow 9.05 to update to 9.40 or 9.60?

Anyone has good experience with ps5 and jb?
