Like KeithP, another Predict Wind and Wind Guru user here.
For critical outings/passages I view all forecasts on Wind Guru, then try to take an "average". At least discard any outliers.
Use PW to visualise wind forecasts relative to coastline.
Both PW and WG also do "swell forecasts", which I also find useful when considering anchorages. However, hereabouts, I find these less accurate than the Wind forecasts. Why?
