I'm not sure I can pick just one.
Arena / Daggerfall - have not played, though I have both.
Morrowind: despite it's age, it's still playable today. Yes, there are some bad quest bugs, and some *very* abusable game dynamics, but despite logging many hundreds of hours across multiple playthroughs, I'm certain there are things I haven't discovered. I sincerely hope the port to the Skyrim engine comes to fruition. I play it again regardless.
Oblivion: Fewer broken quests, and many of the abusable elements of TES3 were addressed - but I really missed the flexibility of spell creation and enchanting of TES3. I've logged far fewer hours on this than TES3 and TES5. Graphically beautiful, but somewhat lacking in quest content compared to TES3.
Skyrim: I've played nearly 700 hours in Skyrim, but there are still some things that fall flat. Graphically beautiful, lots of quest content (albeit some bugged) and I do like the new classless character model. The DLC is a bit lacking - I still haven't played through all of it (I'm about over vampires, and Solstheim seems like a reboot). Skyrim got it right by giving each town a unique flavor and political bent. I like that you can't just bribe someone that doesn't like you as you could in earlier versions - in morrowind a negative disposition was rarely a problem if you had coin and coin wasn't exactly hard to come by in mid- to late-game.
One thing I do not like - Skyrim is "dumbed down" a bit for the console interface. In TES3, you *had* to read the dialogue, your quest log, and some of the books you found for clues. There was a sense of exploration missing from later games. Despite it's other flaws, that's something that made Morrowind great - you actually had to LOOK for things (e.g. that damn Dwemer puzzle box!)
