^ I don't think you've offered proof at all that Thanos used less powerful shields. Galactus doing with a single handblast what PG Champion and PG Thor did while raining blows on Thanos doesn't lend credence to your argument. That's just a statement of fact.
I could state that fact and say that it supports that Thanos used the same or similar shielding. Since, it makes sense that PG Champion and PG Thor raining blows on Thanos compound to about as much damage as a single handblast by Galactus.
And Thanos got slapped like a slut by Odin. Whether he used shields or not ultimately doesn't matter. Weaker characters than Odin (like PG Thor) have destroyed them. This is even moreso true since Odin didn't even go all-out. WHich is obvious since he didn't amp his size, draw forth Asgard's power, look peaked, enter Odinsleep, shake the Multiverzzzzes, etc. Thanos was impressive against a holding back Odin. About as impressive as a slut can look while getting tossed around and failing to do any damage.
