The difference is that Thanos and Ego aren't part of a setting where high end psionics has been established as part of the standard package for cosmic types, like it has been for the Marvel 616 comics. To liken it back to our previous conversation, Ego isn't the Tenebrous in this scenario, he's the Beerus.
I am not saying handling Ego isn't a big deal, it's just hard to say how big a deal. All we can CONCLUSIVELY say is that based on how Mantis handled them, Drax < Ego < Thanos. I think you are right that the empath vs telepath distinction probably isn't worth much, and I could certainly see Thanos taking a psi-assault from Grodd long enough to close his fist and use the gauntlet. It is just hard to draw conclusions from a setting with a dearth of telepaths.
What...the...actual...
But its still nowhere near Asura's Wrath levels of insanity yet.
Thanos floats as he has done it. Question a familiar capes being.
