I always use xargs instead of find -exec because it just comes more
naturally to me. There are some technical reasons for it, though.
GNU xargs is considerably more versatile than -exec. On some platforms
(not sure about GNU find/xargs) find also spawns a subshell for every
file with -exec, which makes xargs considerably more efficient. Not much
difference for a dozen files, but if you have a few thousand results
you're saving the time of starting a few thousand shells that do nothing
but run a single command and exit.
