Were the MCU to use my idea of deities Thanos wouldn't hold a candle to any of 'em. He's just a very high-level mortal, and bleeds when you cut him.
Well firstly, you would be ignoring the 60+ years of Marvel continuity which has included and involved hundreds if not thousands of deities within its stories; not least the Mighty Thor himself and if we use that character as a parallel to D&D, where he is seen as an Intermediate Deity we can gauge the power of many of the gods and higher powers within Marvel.
Secondly, as I originally noted, interaction is more fun and exciting; especially when its hand on. Avengers Endgame (and other stores) are proof of that.
When a deity is on a "whole different level that cannot be challenged" the story just ends right there and then.
But when divine power transcends but is not wholly divorced from what precedes it, then it becomes a more visceral component of the story/adventure/game.
If the Infinity Stones had their own sentience and weren't so controllable by others they'd be more like actual deities in terms of their power levels.
...or perhaps each Infinity Stone only 'doubles' the inherent power within the bearer to control that particular aspect of them (the stones were shown less effective when placed in the hands of lesser beings...although no sense going into comics continuity here as that's a bottomless can of worms).
