Would this have been a close fight or would Kratos win this easily?

"Due to Kratos' immense powers, Thanos' infinity stones won't be able to defeat him. For instance, Kratos' Shield is much stronger than Vibranium or any metal from Marvel-verse, meaning Thanos' Power Stone is not going to work on him.

As mentioned above, Kratos can control time, so Thanos' Time Stone would simply be useless in front of him.

There are other several similarities and differences between both Kratos and Thanos, but from an eagle eye point of view, Thanos might be the mighty God of Marvel universe with the Infinity Gauntlet, but Kratos does have some God-like Artifacts that could protect him from the stones, making Thanos vulnerable." - Got this from the IBT website.
