TS3 is like BTW it is arguably the best album but the glitches made people hate it. It was so hyped that it was never possible for it to slay standards. TS1/2 is TF/TFM. It is iconic and such and was the most successful. TS4 wanted TF/TFM success and resorted back to it with ARTPOP. Unfortunately it missed terribly and no fears the end of the franchise (career).
I don't blame them given the empty state of the base game
