Each model has its strong and weak points, in short-term forecasts up to 48 hours let's say, for south-eastern Europe, like in Greece where I live, in wind (specially in gusts), temperature, humidity, cloudiness, the ICON-EU is real extremely accurate, as well as very good in heavy rainfalls such as storms etc, maybe the best I would say, it does not perform so well in weak local rainfalls, also for short-term forecasts up to 48 hours, the ARPEGE-EU and the NEMS4-12 do very well, NEMS4-12 also good for winds and temperature, but after ICON-EU, and the NEMS4-12 is underestimate the rainfall in this area of Europe, but NEMS4-12 have not so good performance through windy.com but from the parent page, because I think which has more options... for medium-term forecasts, ECMWF is one-way.
