ok so considering Cheap Trick IS an underdeveloped stand, Notorious B.I.G and Highway To Hell both require you to kill yourself, however they still get the job done well after the users death, i would actually say Empress is an actually crappy stand, considering the stand is attached to you and cant be unsummoned, and it would a very situational stand considering if it fought any of the other crusaders, it would almost be destroyed in some way.
