Trunks: “They’re also somewhat different from the androids I know…They weren’t as outrageously strong as this…Even I could fight them fairly well…”

Context: after No.17 knocks out Trunks
Kuririn: “O-one hit..! And he was a Super Saiyan…
Trunks was single shotted by Androids 17 & 18 where he could fight the Future Androids fairly well. This implies a large gap in power between the two Androids.
Androids > Android 18 >> Future Android 17 > Future Android 18 > Trunks Ssj (Androids) > Future Gohan (1 Arm)

Context: after Trunks says Vegeta seems to be doing OK fighting No.18
Piccolo: “Vegeta’s going to be killed…[ ] Watch…Bit by bit, the android is starting to push him back. It’s because his enemy’s power never falls at all, while Vegeta’s stamina falls the more he moves.”

Text box: “Her power is more suppressed than No.17's, but in the end she too is a failure who doesn't listen to orders.”
Androiud 17 > Android 18 >> Future Android 17 =/= Vegeta Ssj (Androids) > Future Android 18 > Trunks Ssj (Androids) > Future Gohan (1 Arm)
Vegeta is much, much stronger in his own time line than he was in the future, and was able to fight the much, much stronger Androids that Trunks forsaw, yet even Trunks was single shotted. Future Gohan would be as well. But not Vegeta. As the fight progressed between him and Android 18, his power began to dwindle because of the newly found Super Saiyan transformation.
Vegeta is somewhere within the power of the Future Androids whereas Future Trunks is much weaker than them.
Vegeta stomps.
