I think it depends on the hospital. If you are at a busy urban trauma center you'll get a very different experience that being at a rural hospital. Our hospital takes new grads into ICU, but not the ER, because there is more stability there when it comes to patient assignments (meaning it is easier to gurantee a new grad won't get thrown the sickest patient on the unit). I have never worked either and have no advice to offer about which is better
