$(( )) is certainly faster in bash, as it a builtin and avoids forking,
but does not work under ash (/bin/sh). As long as you are happy with
bash-isms and nonportable code, definitely go for the $(( )) idiom.
For a comparison:
$ strace bash -c 'echo $(( 1 + 1 ))' | grep fork | wc
0 0 0
$ strace bash -c 'echo `expr 1 + 1`' | grep fork | wc
