Subjectivness and all that, but I liked just about everyone but sera. For me it's something like DA2's companions (Varric and Isabella are just too good) > Awakening (Justice and Anders too good) = DAI (Cassandra, Solas, Cole are all amazing, haven't done most companion quests yet though, fuck sera) > DA (fuck oghren (drunk 24/7, whines about branka), fuck sten (lololol going to kill a whole family because I'm a fucking idiot), fuck alistar and his whinefit at the end, fuck wynn and her partronizing, even leliana isn't that interesting)
