ECMWF is a highly regarded private sector model now used by many pros. They also have a couple of proprietary models PWE & PWG. They do not provide much detail on these models, but in general they take input from existing global models as their starting point and massage the data. I assume they are not full scale forecast models (which are a huge investment to develop and run), but most likely just data tweakers which refine data from the global models (some global models, like GFS, have known weaknesses which could be improved by post processing).

Both are very powerful tools. PW also has tools like Weather Routing, and specific Iridium Go support....giving you singificant functionality that Windy lacks.

PW targets the sailing community as one of its markets so has implemented functionlity specific to that market (like WR and Iridium Go support) whereas Windy is more generalized and does not really target the sailing market.
