Should I get the RSK or the RS30

In Japan and after much looking around I've decided pretty surely on getting a legacy.

Obviously the appeal of the RSK is that it's much faster than the RS30.

My main concern is as you can probably guess the sequential turbo setup. I've seen some stuff online saying it can be a nightmare to work on if you start having vacuum or turbo issues.

I don't plan on modifying the car at all just looking for a fast daily that I can take snowboarding.

Thanks for the help.
