arcos and penitent engines are gross in missions like clense, nightfight, bunker assault, take-and-hold or indded any mission where the deployment zones are fairly close together. with the ability to start within 18" of the enemy, you'll get your hard-core assault units into the thick of it pretty damn fast.
as mentioned, it's great fun using rhinos to cover your approch and block lines of sight.
the sisters themselves can do some pretty gross things too! consider a dominion squad w/4x flamers under the influance of 'devine guidance'! (the one that makes all to-wound rolls of a 6 count as ap1!) even hard troops like termies drop like flies!
seraphim are great fun too; give the superior an eviscerator and they can survive a round or two of assault, but their main use is in their twin-linked pistols and upgrades; either a pair of flamers for more crowd control or else the inferno pistols for tank-hunting.
add in their mobility thanks to their jump packs and you've got a fast response unit which can hop about 12"/turn and if absolutely nessessary, clean up any remnents in close combat. add-in a cannoness w/blessed weapon if you really want the unit to be hard-core in the assault phase, though keep in mind you still won't match the assault prowess of other dedicated assault squads.
cheers!
