Vegito is nowhere near as powerful as half of Beerus's power.Minute: 20
Context: after Goku regains consciousness following his fight with Beerus
Goku: “This ain’t good. The only way to get stronger would be to merge with Vegeta…and even then, I don’t think I could win.”
Significance: Pretty much the same line originally appeared in the extended edition of BoG. The word for “merge” here is 合体/gattai, which in Japanese is used to refer to both Potara fusion and the Fusion dance. Though in Japanese the proper name for the Metamorean dance-style Fusion is simply the English word "Fusion" (フュージョン/Fuujon), this is treated as a proper noun and the process itself is referred to with Japanese words for fusing/merging such as 融合/yuugou and 合体/gattai. Goku even introduces the Fusion dance as a 合体技/gattai-waza, "merging technique", when the concept makes its debut in chapter 469. On the other hand, the process of fusing with the Potara is always described as 合体/gattai, and not with the English word "Fusion" or the Japanese 融合/yuugou.
Goku seemed to have more faith in Enraged Vegeta to fight Beerus than in Vegito. Knowing that Beerus only need 10 % of his power to easily block Vegeta's Garlic Gun with absolutely no damage, Goku underestimated him even when he thought that Vegito can't win against Beerus. It was a preview, but it give us an accurate indication of Goku's thought about Vegeta's power.Minute: 22~23
Context: During the next episode preview, Goku talks about Vegeta's power-up
Goku: "I ain't never seen such awesome power in Vegeta before! I might just be able to see Beerus-sama get serious!"
Beerus (10 %) > Enraged Vegeta's Garlic Gun > Beerus (below 10 %) ~ Enraged Vegeta > Vegito
