There's only one advantage for find... -exec method: compatibility and
lower processes number. It runs command for each single argument.

Two reasons for xargs to be more effective:
1 - As said in previous reply, it may be parallelized with --max-procs
(note, default is 1);
2 - It tries to append as much as possible arguments to each command,
while in system limits. They include not only arguments number,
but also command and argument lengths. Try this command to see:

ls -1 | xargs --show-limits echo
