Does canon indicate there was a vast gap?
"Our lightsabers clash. I try to push forward, only to be thrust violently back. It's like striking iron. There's no give in Vader's arms, and far too much in mine."[...]
"My resources are depleted, my body screaming with pain. I have no hope of winning this fight. He lunges at me; slash and counterslash, stab and riposte. The air is thick with plasma discharge, lights dancing on the edge of my vision. I'm forced back, muscles burning, breath ragged."
"Your powers are weak, old man." Our lightsabers clash. I try to push forward, only to be thrust violently back. It's like striking iron. There's no give in Vader's arms, and far too much in mine.

"You should not have come back," Vader tells me.
My resources are depleted, my body screaming with pain. I have no hope of winning this fight.

I'm forced back, muscle burning, breath ragged. The grip of my lightsaber is slick in my hands, my ears ringing."
This is the whole passage. As you can see, Ben was allready gassed out as of the moment Vader said the line, only after a few seconds of fighting. He even admited that he had no hope of winning. If you call this a stomp or not is just semantics, but it's clear that Kenobi had no chance of winning and there is no parity between them.
Yeah.
Like I've mentioned in other threads, the information we have indicates that Vader's potential remained intact after the events of RotS, and his deeper connection to the dark side made him more powerful than ever(which is likely why Hidalgo mentioned that Rebels Vader = "prime" Vader.)
Also worth noting that even Snoke kept pushing Kylo to harness the potential of his bloodline, in order to become "a new Vader":
When I found you, I saw what all masters live to see: raw, untamed power. And beyond that, something truly special--the potential of your bloodline. A new Vader.
