Potara Fusion

As we all know, Vegeth has never fought at 100% of his capacity...the potara create a true union of body, mind and powers, Vegeth probably could reach the form of SSJ3 (because গোকু was able) and as we saw got new techniques terrifying (like the barrier dosen't belong to গোকু অথবা vegeta but only to vegeth). So my প্রশ্ন is....Do আপনি think Vegeth is stronger than a super saiyan 4?? if we consider that Vegeth ssj is probably stronger than গোকু ssj3 I think Vegetto ssj2 have the same power of গোকু ssj4 and Vegeth Ssj3 is far superior to গোকু ssj4... please leave your opinion with one মতামত :)
