Plain ol' 87.
If given a choice, I'll take the lowest E content possible.

Talk to any tuner and you will see when logging there is quite a bit of knock retard with 87 when under any sort of load...93 and run the same driving and most of that know retard goes away, so you get slightly better fuel economy and power with 93...but it will not make up for the added cost. So it is a personal choice. It will run fine on 87 but with less than optimum timing. Runs best and most efficient on 93.
