Format is the way to go.
Faster, simpler, less lifetime stress on the card.
When you format (simple formatting), you re-write the on-card 'directory structure'
w/ a new pristine directory. So, even though the pictures are still technically on the
card, the card doesn't know it and happily over-writes it.
Deleting is sorta similar and erases the directory entry for each and every image.
Only in rare cases do people bother w/ 'advanced' formatting which can actually write all zeros or random garbage to the card (so the images cannot be recovered)
