It is cleaner, but it is not any quicker - and strictly speaking neither
is a rule - they're preprocessor expressions that result in the exact
same sets of four rules each (which is why the speed stays the same).

However, this is quicker (commands re-ordered):

A0,[!@..., Az,\0,

And this is quicker yet (simpler commands):

^[!@... $\0
