Bonzo here - we have more cookies than Tesco's biscuit aisle!
It was a while ago but we found that Cocoa beach was made up of small shells - very painful on the old feet, and the only shop of mention for miles around was Ron Jon's.
Daytona on the other hand was wonderful, especially as you could actually drive and park on the beach. There's no danger as the beach is sooo wide.
Just remember that both beaches are on the East Coast i.e. The Atlantic Ocean - not the smoothest or warmest of seas ever! - brace yourself for massive rollers.
Like I say - all notes are JIMHO.
