There isn't any need to escape the '+' character.

  time find rm -type f -exec rm {} +

I definitely recommend using -exec rm {} + over using xargs because
the find method has been incorporated into the POSIX standard.  All
operating systems will have it.  The xargs -0 method is a GNU
extension and won't be available portably.

Once you decide to use GNU extensions (such as xargs -0) then you
might as well use a different GNU extension and use -delete instead.
In for a penny, in for a pound.  Using -delete is almost certainly the
fastest method since it doesn't spawn any external processes.

  time find rm -type f -delete
