True, being existentially limited sounds like a terrible limitation. But potara is permanent, I think that would be worse. Considering even after you defeat the villain you're stuck like that (unless you have someone who is similar to buu with you).
Vegeto has already been stated by Akira as stronger. Anyone who says Gogeta wins because he has ss4 is overlooking that a hypothetical fight has hypothetical means. SS3 Vegeto vs ss4 Gogeta, Vegeto wins. SS4 Vegeto, creates black hole destroying the entire universe, because he is the spiral nemesis

Limitations: Gogeta - Lasts for only about 30 minutes Vegito - Permanent, hence, no more family to return to until DB Super Ep.66 reveals that non-Kais will only be fused for about an hour.
