Kings fall was ok, but for me it got boring very quickly after the ship jumping bit. Very mechanic orientated and all shoot stuff everyone stand in here,shoot stuff everyone stand here and again and again etc etc. Try the vault of glass raid. Nostalgia may have an influence but to me it's the better raid, the feel,the atmosphere,it has, it feels like a raid. Crota used to be (still is) alot of fun even though now it's more like a strike. Wotm is ok, but even the first time doing it it had the feel of ' I have been here before' . it also gets boring really quickly, and apart from the siege engine it's very nearly the same mechanic all the way through. Give them all a try though,with the right people you will have fun.
