Not any different from their Boo Arc selves, except for the boys, the humans and perhaps Vegeta. Throughout the later half of the series it had been stated all these characters were reaching their peaks
Goku makes it pretty clear he's confident that he and Vegeta can become far stronger through training though.
Chapter: 516 (DBZ 322), P11.2-3
Context: after Polunga restores Goku’s stamina and he’s about to finish Boo off with the Genki-Dama
Goku: “…You’re amazin’. You hung in there really well all on your own…This time, be reborn as a good guy…I wanna fight you one-on-one…I’ll be waitin'…
And I’ll have gotten much, much better…See ya later!”
Chapter: 517 (DBZ 323), P5.4-5
Context: after Goku tells Dende to heal good Boo
Goku: “Well, it’s alright, ain’t it Vegeta? This Boo and Mister Satan both did well. If these two hadn’t been here, then we and everyone else would have been done in. Right?…And if worse comes to worse, we can just fight again.
Let’s train so that this time for sure we won’t lose even if we go one-on-one.”
