A lot of people misunderstand Thanos here.
When Thanos supposedly fought Odin, he came there to find a "cure" for Thor. When he faced Tyrant it was because he wanted to test him and see if he could withstand his attacks, which he could. Thanos himself mentioned that Tyrant had been humbled. But enough about that for now.
I'd say that Surtur should take a solid majority against Odin barring Odin's ability to lock him away/imprison him. Seeing as Tyrant has shown NO magical abilities, I doubt he'd be capable of imprisoning Surtur.
Surtur does NOT employ any technology, nor does he use biospheric energy. Which means that Tyrant won't be able to absorb any of his energy or take over any of his technology, like he did against Galactus. Which makes that fight irrelevant. So please stop listing it as a feat.
Surtur's magic has given his immeasurable knowledge and intelligence which should give him a pretty major advantage. The likes of Terrax and Ganymede would not be able to harm him, and despite what most people think he actually has impressive hand to hand skills.
I'd say that Surtur takes a solid majority here. If he chose to engage Tyrant physically he would most certainly win. 7/10
