The sleeved bushes have an arc of operation, hence the FSM instructs that they be torqued when on all four wheels, else the rubber will tear away from the bond it has with the sleeves, in essence they are a bearing and because they are rubber are more forgiving than rose joints which, as Frank says, are good for track use.
If articulation gets well over standard, then maybe the poly bushes are better, because they are even more forgiving than sleeved ones given neither inner or outer sleeve is bonded. In theory, this will detrimentally affect handling, though I have read that if they are badly made, I.e. too big and the sleeve is narrower than the bush, then when they are torqued up, they lock the joint up......I've no experience of that, though it makes sense.
