Same here, and I'm one of the biggest Vegeta fans out there.

Frieza kicking that blast away was physical strength AND, Frieza TANKED the 20 times kamehameha. Remember, 3 times Kameha bad enough power to destroy Earth...Frieza tanked an attack 4 times that and was only mad because he was pushed back.
Superman got koed from the shockwaves of a minor planet busting attack.
I think it's just that Saitama was made to poke fun at Manga like DBZ. He justs powers up above whatever the next challenge is. He would just punch him harder and it would be over.
