The CD of E is half the CD of Q and gets an increase of slow with levels. Also, getting 2 E's during ur ult does more damage than a Q (did a small calculation with 15 bonus AD), with the 50% increase from a second hitting the same target. Finally, landing E is easier than landing a Q, no less than 2 on the same target.

Nonetheless, maxing Q first is also viable with the energy cost decrease with level. At the end, it comes down to personal preference.
