Skyrim. I would say Morrowind if it didn't have such a shit combat system. even after playing hundreds of hour with it i still didn't like it. Oblivion suffers from having a boring empty map with procedural generated dungeons. And a awful level scaling system.
Skyrim avoids those things so it ends up being my favorite despite the lack of features from previous games. It also has a better radiant ai system, A better third person mode, And better combat (for the most part) than the other games.
