1. Nohorito Sumitomo's soundtrack for Dragon Ball Super is one of the best soundtracks in the whole franchise and his work on Super: Broly is phenomenal.
2. Dragon Ball Super: Broly's art style gave Dragon Ball a much-needed new look. I personally don't like Yamamuro's character designs.
3. Not to shit on GT, but Super did something GT failed to do: make good use of everybody. In both the manga and anime, all of the Z Warriors got their time to shine, especially Vegeta. For the first time since the Cell Saga, Vegeta has a transformation exclusive to him and only him.
4. We got to see what happened to Future Trunks' timeline after Dragon Ball Z, and the return of an evil Goku spiced it up even more.
5. Goku Black was actually a really cool villain, and he even got what he wanted; which only Lord Slug and King Piccolo managed to do.
6. Super Saiyan 4 might not ever be coming back in canon, but Broly's Ikari form is a nice little homage to it.
7. Super has some fantastic concepts, which fans have created their own stories about. If they were fleshed out more, we'd have an incredible sequel to Dragon Ball Z on our hands.
8. Whereas Dragon Ball Kai failed to continue the momentum that Yo! Son Goku and His Friends Return!! had started, Battle of Gods, Ressurection F, and, by extension, Super, managed to bring back and amp up the momentum it had.
9. Vegito's return. Just..Vegito.

10. Sean Schemmel and Christopher Sabat screaming their lungs out will never cease to amaze me. Seriously, how do they hire Dragon Ball voice actors? I bet they're like
Toei: あなたは長い間悲鳴を上げることができますか?(Are you good at screaming for a long time?)
Random voice actor they found on the street: はい、できます。 (Yes, I can.)
Toei: すごい!あなたは採用されました!(Great! You're hired!)
Need I go on?
