Not by a long way. God of War takes the cake on that front.
Odyssey exceeded my expectations. I was surprised by the reception and bought it. Its the best game in the series on current gen consoles, though I haven't played Unity fully patched up which was the way it was meant to be played.
I don't really consider God of War 4 to be an RPG personally. Officially it's considered to be action-adventure from what I see on wikipedia. While it does have some RPG elements like a rarity tier loot system, it's missing others like character choice, romance options, etc.
