Lohse has the best story by far. Most unique, well written and well woven in.
Sebille is probably my second favourite after Lohse.
Beast was a total disappointment. Playing as him, I did not feel like he provided any additional content into the game.
Fane is good but a bit disjointed at times. Good lore value.
Ifan felt a bit meh. His story is well integrated but I just found him a bit boring.
Red Prince is a chump and the least amenable from the lot. His story is solid, but you can do the bulk of it without having him on board.
e: forgot to mention - Lohse's downside is the shit conversation tags. I only used Jester a couple of times because the "jests" are beyond awful. Mystic is unremarkable.
Scholar is the most useful conversation tag by a long shot, meaning that it is helpful to have Sebille/Fane in your party. Not having this simply locks you out of a bunch of quests (e.g. Bloodmoon Island vaults) or does not allow for the best quest outcome (e.g. A danger to herself and others).
