It may be misleading to say that the text mode is more powerful. Actually, it depends on your use-case. For example, having seen the perms of a file, if all you wish to do is add/subtract perms, then obviously text mode is the way to go.

However, consider this use case. You `ls` a file (not necessarily with the `-l` option). AND, you wish to give it some absolute perms REGARDLESS of WHATEVER perms it currently has got. Then, if have been a *nix user for a while, you could simply use the number mode. Yes, you could employ the `=` operation of the text mode too, but it would be more verbose -- and as someone pointed out... slightly slower also -- than the number mode.
