Tech is definitely a must have... M Drive allows for much quicker settings adjustments and you will enjoy MDM mode if you plan to get an SC. It will give you enough leeway to enjoy the car without worrying about getting too out of shape. With DSC fully on, you will be cutting power everywhere.

Remember you also get more throttle adjustability with Sport Plus and a Sport steering setting with Tech. Those settings are not obtainable without the package.

If you were just going to get EDC alone, consider just adding coilovers later on.
Thanks for the feedback. My comment about the engine mapping comes from experience w/ Subarus. For instance, you wouldn't choose a factory option for an aggressive tune on your WRX, if you knew ahead of time that you'd install an STI turbo and have the car retuned on a dyno anyway. But it seems that M drive is much more sophisticated than simple engine mapping.
