I use ECMWF but never even knew what was different - def more reliable where I am for cloud / sun. Haven’t paid attention enough to see if it’s wind predictions are better

Some differences are covered here: https://confluence.ecmwf.int/download/attachments/53517138/P... (2016)

I once had lunch with a senior meteorologist at the WMO, who was (5 years ago) convinced that the European model was 5 to 10 years ahead of the US model and that it would be hard for them to catch up. Not sure if that's still the case.
