The level of engine modifications combined with your driving habits will dictate what gearing you like best.

A 915 won't work for you if your engine is modded past 300RWHP and you don't like to buzz the motor.

If your engine is stock you will think you picked up 100HP with the 915. Turbo lag goes away with the short gears.

The 915 is weak. It will not take drag racing starts or sustained torque levels of much more than 300ft/lb for the long haul. If you have a stockish engine and drive reasonably the 915 can be a lot of fun for many years. If not you will blow it up in short order.
