ag_UF does have raid frames, but for me personally, nothing beats grid; incredibly compact and functional, just takes a little work to set up.
oRA2 has target management frames, as well as res monitor. It does not have an emergency monitor.
Finally for cleansing I suggest a combination of Grid and Clique (not ace2). Clique is a click casting mod that works with Grid and many other unit frame mods. Set up grid to highlight debuffed frames and then set up clique to bind your cleanse spells to a mouseclick or mouseclick + keystroke combination.
