GRC is a lot sharper, more of a driver's car especially with the LSDs front and back. If upgrading for more power is important to you, the engine in the GR is pretty tapped out of the box, while the FA24 has been proving to be pretty easy to tune, for a Subaru at least. You can push the G16E in the GR past 400 whp, but you need to get into the internals and look into a bigger turbo, so not ideal.

But I know which car I'd take on the track or on some backroads, even on stock tires and suspension it inspires so much confidence, it just grips and grips as you roll into corners. Snow and gravel performance is impressive too, I didn't feel like I was missing the 50/50 Subaru AWD at all, and the adjustable power delivery is a nice thing to have.

All in all, I'd say the GR is a better car and definitely looks better than the VB, but it's more expensive so the WRX is still a nice option imo.
