I've done research into this for my own projects, and
json_encode/json_decode is *slightly* faster than serialize/unserialize,
but unless you've got 10k+ objects in a list, it's really not worth it.

(FWIW, I use json_encode/json_decode personally, since I'm storing 100k+
objects in a list. It's still only slightly faster, and certainly not
worth rewriting everything.)
