Both.
Generally, Orthodox Albanians live in south Albania, Kosovo is mostly Muslim, with some minor RC. Experienced people can easily tell by name wether Shqiptar (the name Albanians call themselves) is Muslim, Orthodox or RC Christian.
In Albania, Enver Hoxha tyranical regime abolished religion but in reality destroyed Christian base on behalf of Islamism. Also, forcibly integrated Hellenes, Vlachi, Serbs, Montenegrins into Albanian nation. There was a large Serb and Montenegrin minority in Albania after Albania was created. Almost none remain today.
Kosovo Shqiptars do not share that experience because they were free to express religious beliefs.
What I would really like to learn is about Orthodox Christian Shqiptars in Kosovo. I strongly suspect they were the victims of geneocide by their fellow Shqiptars during WWII.
Now, imagine being an Orthodox Shqiptar and watching destruction of Orthodox shrines in the name of Shqiptaria( Albanian Nazism).
