the mat is self normally doesnt bother me its was always the all weather mats in my wrx that annoyed meWell you can try swapping the two front ones and see if they work fine. I personally hate floor mats, so I never have one on the driver's side. I'd rather just let the carpet rip up.
If you want something Subaru-ish, there's always cheap knockoffs.
