I disagree.
Not gonna deny a lot of people like that aspect of it, but let's not also pretend people don't know the series is just as silly. Buu's super popular for a childish gum demon that turns people into candy lol.
Being silly doesn't negate the more " trying to take its self serious" parts from existing, in fact I would say they make you appreciate each other.
Its why I like the new day and dust rhodes. It makes me appropriate when cool shit happens. I like both those elements, but I feel like it comes back to big dudes cutting promo's and telling eachother " they are strongest there is"
It also helps that the last episode of dragonball super is literally just that, and the folks from the green lantern universe even had lights and colored smoke
Beerus is a humorous, endearing character that's obsessed over food who also can destroy a planet if he gets serious. That's also Dragon Ball to a lot of people, and that's why he's really popular, even outside the fandom. (At least, from my anecdotal experience lol)
If you think that's what dragon ball is, i'm not going to stop you. What you desribed, is a generic shonen protagonist, almost every generic shonen protagonist as " guy who's kind of funny who can eat and when he gets serious he gets cool" . That isn't unique for. If that , what DB, DBZ, super whatever is to you, that's fine.
For me it was always about this bombastic characters, varying in personality in wild crazy outfits, every sentence coming out of their mouth sounding like they are cutting a promo, having these crazy fights that didn't need to happen with jumps in logic, but due to the charisma of the characters, they sold me on. I put my hands up as a kid watching goku, cheered on vegeta when he turned super saiyan. I was boo-ed every time general blue came on screen. They were these larger than life wrestler guys for me. Even back in dragon ball.
That's how I see dragonball, and that's why I love it. You can feel free to love it for different reasons, that's totally fine. DB isn't the only one too, its why I like fist of north star, its why I like bobobo for breaking down fist of the north star into just being basically that. Glorified wrestler, for me is a giant compliment. Because I love wrestling, and I love DB.
