jQuery equivalent of YUI StyleSheet Utility?

Found a couple that look like they do similar things. I haven't tested them. jQuery.Rule looks to be pretty good though

jQuery.Rule by Ariel Flesler

This plugin allows quick creation/manipulation of CSS Rules, in a "jQuery-way". It includes features like chaining, iteration using each, selectors with context.

GlobalStylesheet by Jeremy Lea

Enables CSS modification that uses a 'global' stylesheet, rather than inline CSS. This is particularly handy for modifying CSS styles that you want to remain persistent until a page is refreshed again.
