I've only seen bits and pieces of Super, but honestly I'm just not interested
Mind you, I'm of the viewpoint that the real peak of the series was in the Piccolo Jr. saga of the original Dragon Ball, either that or the Frieza saga in DBZ(Kai). The fighting was a lot more grounded in martial arts and there was more emphasis placed on the choreography, which made them more interesting to watch. The moment everyone is able to fly indefinitely and fire energy blasts, the fights end up losing a lot of their depth and everyone starts feeling the same, even at different power levels.
This isn't even getting into the plot, which I think starts to slowly sink somewhere in the middle of DBZ. Reasons why:
* After Namekian Dragon Balls were introduced, I felt that the concept was abused to the point where it was impossible to feel any tension in a character dying, knowing that sooner or later anything bad that happens to the dragon balls is going to be retconned by an even stronger set of dragon balls.
* Character interactions become muddied after Dragon Ball ends. Interesting side characters such as Puar, Oolong, and Launch become lost to time because they no longer have any utility in DBZ's expanding universe. This goes the same for once potent fighters such as Yamcha, Krillin, and Tien, to the point where it's a wonder that they even appear in fights anymore.
* This kinds of drives into the next point, which is the fact that the series is defined by power creep, which is what causes it to suffer the most. It works well enough in DBZ since extraterrestrial life was only just introduced at the beginning of Z, but after the Frieza Saga it just becomes incredulous. The Cell Saga would have me believe that the Red Ribbon army, which couldn't even handle Kid Goku in season 2 of DB, could just up and kill every Z fighter sans Goku himself simply by researching fighters underground? Or, in Super's case, that two underdeveloped grunts that were under Frieza's rule would become as strong as Frieza, who during DBZ was ten times stronger than any of his underlings? And that kid Trunks is supposed to be even stronger than that? The sense of power scaling is just completely lost on me.
I honestly think that Goku's story should have ended after he first became a Super Saiyan. That felt like a proper climax, and if all the dragonballs were destroyed then it would have extra impact. This isn't to say the series should have outright ended there, but it could have gone a completely different direction, like following a different character's adventures up until DBZ. Instead of expanding forward, why not look back on characters with not as much strength as Super Saiyan Goku? What if there was a Dragon Ball series that focused on Vegeta's adventures, while he was invading planets under Frieza's rule? Even just in that example, there's plenty of potential writing material to work with.
