I was referring to movies that corresponds with each arc in the series like for example how would Goku from Cooler's Revenge fare against Final Form Frieza for example.
Then that would mean having to know where each movie would logically make sense to happen in the series. So let's try this then:
Dead Zone: This one is easy, it's Goku before Raditz came to earth. He wouldn't be much different from when Raditz came to Earth, in fact, he might actually be weaker. In any case, alone he's not going to do on his own, and would need Piccolo like in canon.
World's strongest man: This should happen after the saiyan arc, as Goku knows the kaioken. But Piccolo is alive, so I'll assume this is an alternate timeline where Goku managed to arrive before Piccolo died and they manage to kill Nappa, and even Vegeta. Although it's more than likely that Vegeta was spared. Goku here should be as strong as he was against Vegeta, if not stronger due to the zenkai he received. He shouldn't have trouble with Vegeta as long as Vegeta doesn't turn into the great ape.
Tree of might: This one is trickier. All of the Z fighters were alive, and Goku was confirmed to have a powerlevel of thirty thousands(I don't remember if that was his base power or him using Kaioken) by Turles. In any case, if he can handle a good kaioken times ten(Which I doubt he could), he would be able to take on the Ginyu Force, granted that he doesn't let Ginyu change his body. Frieza is out of reach for now. But one thing for sure, he can take out any Namek villain except Frieza and maybe Ginyu.
Lord Slug: Personally, it depends on how strong Slug is compared to Frieza. I like to believe Slug is stronger than any form of Frieza save his last one, so Goku can beat Frieza if he goes for the kill. If he uses FSSJ or Kaioken times one hundred, I can see him easily pulling out a victory. He won't win if Frieza is using all of his power or at least 50%, however.
Cooler's Revenge: This one is fairly easy. Cooler himself stated he could see how Goku beat Frieza and that was with him using Kaioken times twenty. So Goku here could beat Frieza 100% with kaioken, no need for Super Saiyan.
Return of Cooler: Vegeta is a super saiyan, so this means the android arc. Android 19 and 20 would be defeated, but I can't see Goku defeating either 17 or 18 in this movie.
Super Android 13: Once again, this should be android arc Goku before the hyperbolic time chamber. I think he's not even the strongest hero there, it should be Piccolo because I remember him being fused with Kami at this point. Unless Goku is stronger than Piccolo here, he's still not beating 17 or 18. If he is stronger than Piccolo, though, He should be able to beat the two of them. Maybe even 16 or Imperfect Cell after absorbing the humans.
If he absorbs the Genkidama, however, I'd say he could have a crack at even Semi-Perfect Cell, or even beat him.
Broly the legendary super saiyan: Cell Games arc, most people put the arc during the wait of the ten days leading to the Cell games. Thus, Goku should be as strong as how he was against Perfect Cell, so he wouldn't fare any better. If he does get the same power he used to beat Broly with, though, he should be able to beat Perfect Cell handily, and maybe even Super Perfect Cell.
Bojack Unbound: Easy, Still should be Cell Games arc Goku. So he's not winning against Perfect Cell.
Broly Second Coming: Buu Saga Goku. Wins against Fat Buu/Kid Buu if he goes all out but loses against any other form of Buu.
Bio Broly: Should be the same as Goku from movie 10, so, he's still not beating Super Buu or his forms.
Fusion Reborn: Now this is where things get interesting. In this movie, Goku was able to hold his own against Super Janemba, but it was clear that he was outmatched and that Janemba was toying with him. Still, Toei confirmed that Janemba was indeed stronger than Hirudegarn, who beat both Ultimate Gohan and Gotenks with ease. So, It's safe to say that Goku might beat Super Buu, but any other form is too much for him.
Wrath of the dragon: Easiest movie to place alongside Dead Zone, Goku after the buu saga. This Goku should be able to beat Super Buu handily, and perhaps even Buutenks, given he beat Hirudegarn who beat both Gohan and Gotenks, a feat that makes Hirudegarn as impressive if not even more than Super Buu with Gotenks absorbed. The question is whether this Goku can beat Buuhan, and I think he could manage it with a Dragon Fist.
