SS Future Gohan. That version of Vegeta got owned by 18 embarrassingly, but Future Gohan could hold is own against both of them even if he did lose an arm.
Bare in mind, Vegeta would have trained in the three years up to the androids coming because he wants to surpass Goku, so I wouldn't be surprised if he was about the same strength without Trunks travelling through time.
Do not forget the fact that the androids from the future timeline are explicitly vastly weaker than the androids in the cell arc. Trunks says the androids in the present are “much, much stronger” than the androids from the future. And ultimately Future Gohan was still getting his ass kicked by the future androids
