I personally think oversaturation of weather resources has clouded the picture; with every storm, every pattern change, you have a breadth of Ops and Ensembles, a ton of websites to look through things, all fed through forums and twitter where people are trying to contextualize everything in real time. The truth is the models are fine, they have not degraded; I think the Euro has a slight edge and i prefer for it to be on my side in big ticket events, but the GFS is plenty useful too. GFS is the Kirk Cousins of weather models.
