I have a server, its httpd.conf already has some \"RedirectMatch permanent\" directives in it.

As the accepted answer says: mod_rewrite can do things which mod_alias can't. However the main benefit of mod_alias is that it is easier to use.
The apache docs say that we should use mod_alias for simple things like redirects and mod_rewrite only for things we cannot do with simpler modules like mod_alias. View the docs: When not to use mod_rewrite.
