Frieza showed massive progress after his image training in hell, and not just with controlling the stamina of his Golden form. If he was the same newb Gold Frieza from RoF, the results would not of been in his favor like that. They pretty much equalized him to Goku (minus the Kaioken hax I guess which Goku uses sparingly), at least at the time to show he would be a powerful addition to U7.
Now, with UI and Vegeta’s SSJB2, they did surpass him.

Freeza's power has grown immensely since RoF -- and when you think about *how* his power grew, it's even more staggering. Back in RoF, it was everything Freeza could do to contend with a *n00b* SSB Goku, before he eventually fizzled-out thanks to the shit stamina of his Golden form back then.
Fast-forward to just before the ToP, however, and Golden Freeza was every bit the equal of a SSB Goku who has: a.) *fully perfected* the SSB transformation, b.) has underwent at least THREE days/years in the RoSaT, and c.) has gained multiple zenkais thanks the the numerous fights he has been involved in since RoF.
...Yet Freeza's power skyrocketed that much just by THINKING about fighting whilst he was trapped in hell, ffs. The dude is a prodigy like no other... Not even debatable.
*As for Freeza's physical durability: it IS the best in the series, pound-for-pound. Regeneration/healing-factors are obviously not indicative of raw physical durability... Boo's body, for example, is not as durable as Freeza's... This isn't a difficult concept to grasp.

Nope... if Beeres would not arrive, Hakai would eventually get Goku, but of course, wouldn't destroy him at all. It would be similar to what happened to GF against Toppo... it would hurt base Goku and Goku would already come back as UI in episode 95.
