The 94 octane (assuming AKI rather than RON) is worth it if you are tuned and running a little more ignition advance or the car sees hot laps on the track -- otherwise, I doubt you'll find much of a difference in power either.
On the other hand, it certainly won't hurt -- what's the price difference compared to 91 and can you get 93?

At the end of the day, use whatever octane you like as long as it's premium being put into your Z. Now, if you're someone to complain about the difference in price per liter, why buy a sports car?
