The Yo! special is canon and in that movie Tarble said that both Abo and Kado are just as strong as Frieza was. Then we see Goten and Trunks fighting them in there base form and where pretty much equal. The question here is at what form did Tarble mean when he said that they where as strong as Frieza. Remember Tarble never saw Frieza in his final form, not even the Ginyu Force so i'm guessing that Abo and Kado are just as strong as Frieza was when he is at base form meaning 530.000. Or Tarble somehow knew about Frieza's true form and power and was referring to that so if thats true than Goten/Trunks at base lvl are just as strong as Frieza is in his final form.
Remember we have Goten/Trunks fighting Android 18 in the main series and they where doing decent against her so that has to mean that Goten/Trunks base lvl are definity not at 530.000 because the SSJ multiplier would bring there PL upto
26.500.000 while Frieza is at 120.000.000. The boys could't even stand up to Android 18 witht hat kind of PL. I'm gonna say that Goten/Trunks base lvl are around Frieza final form lvl, i mean after Frieza died everybody became so much stronger its not even funny. Freaking Goku in base form when he fought Frieza was at 3 million and he managed that after just a couple of months of training in his space capsule traveling to Namek and then recovering from a serious injury (Ginyu fight).
Add to that the 3 year training against the Androids, the 1 year in the Hyperbolic Time Chamber and the 7 year of training in Other World + various zenkais. Yeah Goku at base lvl imo should be able to take down Frieza.
