Etz is Biblical Hebrew; ilan is Rabbinic.
Also, etz is ambiguous, since it can mean "tree" or "wood." Thus Rashi (to Gen. 18:4) finds it necessary to gloss תחת העץ as תחת האילן, to make it clear that Avraham was inviting his guests to rest under the shade of a tree rather than under a wooden canopy or something similar.
