I live in the area, so I understand how you feel. Having an accurate depiction of your local area is important.
I have Vector and PNW installed, along with DreamTeam's CYVR. The coastline and surrounding area is exactly as it should be.
I would suggest keeping Vector as in general it does a great job adjusting coastlines, etc.
If you purchase PNW (right now it's 50% off) I think your issue will be resolved.
