It really doesn’t make any difference. Depends more on how you use you camera. In my case the camera (I only have one at a time) is stored in a grab and go bag and my desktop computer lives in a different room. Also I don’t use large cards rather a number of 64GB cards which hold more than 1K raw exposures each. When I come back I swap a newly formatted card for the card in camera and take it to the computer reader to import and format. And, yes, I do format the card in the computer. The reason the manufacturer says to only format in the camera is to keep you from using wrong format and blaming them. By design rule for interoperability all cameras use FAT formats which differ by max file size. Windows format function defaults to the proper format for the card so it is hard to screw it up. Also I use the volume label to keep track of number of times a card has been formatted in the event the card fails. I have never had a failure even with one (SD) that is 15 years old and been through the wash once and not through the dryer. I have a little script that does a quick format and increments count that I run right after LrC completes the import. Given its UNIX heritage I assume the Mac OS can do the same. Whenever I put one of my cards in a Mac to be read it adds a file I do not recognize. It seems harmless, however.
