I don’t think LOTR is as clear-cut as many people think, but it’s certainly more idealistic than GOT.
I prefer LOTR but I’m glad both works exist. I don’t think GOT is better than Tolkien as a whole, but it’s certainly much better than Tolkien at giving a detailed portrait of a believable imagined society. Tolkien just wasn’t interested in stuff like politics or economics.
A case could perhaps be made that GOT is more orthodox than Tolkien, at least if we define orthodoxy in terms of St. Augustine
That is to say, in Tolkien evil is seen more often than not as an external force. People can be tempted, but much of the time the temptation seems more like what we would imagine it to be for unfallen human beings. Aragorn could choose to be evil, but he doesn’t seem to have any very strong pull in that direction. Evil is presented as something we freely choose. I don’t think the books are necessarily Pelagian, and I love them dearly. I’m making a devil’s advocate case here, so bear me out!
In Martin’s world, on the other hand, everyone is more or less broken. Most people are mostly corrupt. There are good, noble characters, but even they make terrible mistakes and their good intentions often lead to disaster.
This makes for much less uplifting reading, but arguably it’s quite compatible with an orthodox Christian understanding of the human condition.
The “faith of the Seven” obviously has some analogies to medieval Catholicism, but its basic beliefs actually look more like a very institutionalized version of Wicca (including the maiden/mother/crone thing). Arguably Martin does have an anti-monotheist bias given his portrayal of the worshipers of the “Lord of Light.” But this would apply to Islam at least as much as to Christianity.
Martin is an atheist, and his portrayal of religion sometimes reflects this, but mostly in unintentional ways. He clearly wants to portray religion as a real, serious part of people’s lives, for good and evil. One very troubled character who first appears as a monstrous villain and then becomes somewhat more sympathetic appears to have become a monk, and this is portrayed positively.
The strength as well as weakness of the books is their focus on politics and on the ways human beings hurt and destroy each other. They are very, very dark. I don’t think they are “depraved smut,” but I would not recommend them without some caveats. I myself needed to take a long break from them.
