Definitely totality, and the ethereal light a minute or so before and after.
Saw the aurora this year for the first time too, in Iceland (check your 2013 IIS calendar, April I think

). Very impressive and spine-tingling too, but after seeing the TSE, it's definitely 2nd place. (And seeing it from a plane doesn't count, believe me!)
Missed volcanic eruptions twice by only a couple of months, Eyjafjallajökull in 2010 and Rabaul in 1994 (though that one was probably a good one to miss

).
