First picture is the Bulgarian greatcoat, they are rather nice although will need to be aired out because they nearly all where stored with moth deterants which smell a lot. A good wool lanolin agent will help get rid of the rough nature of the wool they used. I have a small collection of military greatcoats, Finish officers greatcoat is one of my nicest if you can even find one for sale. British greatcoat from WW2 is also very nice but those are mostly heavily worn these days. The warmest is a Russian bekasha/tulip sheepskin coat. Not sure if you can even get them anymore because well of recent events but those coats are good to any temperature on Earth or any wind condition.

Polish greatcoats are very similar to British ones but are in better shape generally speaking and cheaper. Any of the European style greatcoats are all pretty good though, Austrian ones are a bit thin but they are still nice.

For new coats this is probably the best value for money you can get if you want a new greatcoat. https://www.varusteleka.com/en/product/sarma-wool-coat/61689
