Of the ones mentioned, if you're playing through the story with friends I'd go with LotRO, SWTOR has good story but it's quite single-player focused outside of Flashpoints and Operations.
TSW seemed like it has good story but I never played too far because I hated the combat, so not sure how it plays as a group.
GW2 is probably a good option if you dont mind B2P. Plenty of group content although the story is a bit hit and miss.
