Judging them by their old school games, Elder Scrolls just because I played Arena and Daggerfall a before I played Fallout 2. Judging them by their new school games, Fallout because New Vegas was a wonderful game that actually felt like Fallout; plus I never sunk as much time into Skyrim as I did the Mojave and the DLC is just so well written.
As a series on the whole, I would say they're pretty much even. Fallout provides excellent narrative and deep characters--both in the NPCs and PCs--four out of the five games (Tactics <3); while TES provides an excellent world with really interesting lore and, in the case of Morrowind, really unique plays on the High-Fantasy genre.
Choices are hard.
FAUX-EDIT: SPECIAL is modified GURPS and I love GURPS, so perhaps Fallout really does have a slight edge in my mind. Then again Arena and Daggerfall were essentially DnD on the PC...
