Ok, you are using thor and thanos fight as evidence of thanos taking high level hits right? That room that thanos and thor was fighting in would have been turned to dust if frieza was inside of it punching thanos. Do you want to know why, because frieza was creating nuclear explosions with his fist while fighting goku. He then proceeded at punching goku some more which sent VISIBLE shockwaves around the planet that was disintegrating rubble.
Frieza blasting power AND his punches would open up thanos shields... especially if he do a couple of hundred nuke punches in a sec on the shield along with blast that creates atomic bombs explosions. I have never seen thanos shields tank anything like it.
Then we have frieza tnking sh** that was stated as having enough power to shed the planet namek and him tanking punches that shook a planet twice the size of earth with him getting up with a smile on his face.
Thanos by no means is one shotting him and his shields would get crush and frieza punching power would drop him since thanos has never withstood punches that isn't CLOSE to what thanos can deliver.
I don't know why you are bringing up thanos speed. Thanos isn't touching frieza and surfer or anyone else that thanos has fought doesn't fight any where close to what frieza can fight at.
