What if GT came out today but worse?
This is what Daima is. Characters turn into kids, they look for Dragon Balls, there is a red dragon, Goku turns Super Saiyan 4.
If you have seen GT, there is generally not much reason to watch this except you need more Dragon Ball or want Vegeta to use Super Saiyan 3.

Generally people excuse this by saying this is canon or its good because Toriyama has written it. You need to remove that mindset and realize that it doesn't work that way. There are way too many contradictions in the show that make it impossible for Super to continue after this. Either one is canon and the other isn't or both aren't canon if you use that mindset.

What about the humor?
It is ok. It is not really Dragon Ball funny but you do get good laughs unlike in Super. Sadly, the jokes are so mediocre that often I had to turn of my streaming device and do something else. Not a single episode was good enough to keep my attention for long

The fights were not really impressive either. There were no antagonist that gave me the feeling of "Oh no, what they are gonna do?". I don't know if that was because of knowing how Dragon Ball ends or the atmosphere of the show. If you look at Dragon Ball GT, you felt like there was something at stake when Goku fought Baby or Omega Shenron. If you look Z, you felt like things are real.
But in Daima, the enemy can be a billion times stronger and you still don't feel there is anything to worry about.
Thus seeing Super Saiyan 4 used against these kinds of foes feels hallow.

There is also a plot device introduced really early that should introduce fusion that was never used once. So don't get your hopes up.
There is another retcon to Boo's origin which makes it the 3rd attempt to come up with an origin story for Boo.
Due to budget issues, while they gave Vegeta Super Saiyan 3, they changed its design in a way it doesn't look like how Super Saiyan 3 should look.
New Super Saiyan 4's introduction is underwhelming taking away everything what made the original special. It has a design change too so it is not the same as in GT. Which just means they put a pallet swap on it like with Super Saiyan Blue and made certain body parts different.
Sadly, not even Daima is safe from the lasers guns that could harm Super Saiyan Blue Goku.

Generally it is better than Dragon Ball Super. I mean its hard to make a show worse than Super but it is still not good. Super was awfully bad but at least it kept you most the time watching to figure out what will go wrong next?
In Daima everything is so mediocre and doesn't stand out. If it was Dragon Quest, nobody would watch this show.
While people start calling it a 'better' GT, I question how? There are like at most 2 'good' episodes but that depends on how much you enjoy transformation sequences and maybe fights in final forms.
Like my favorite Cell Saga episode is the Drivers license episode but most think the best part is Gohan going Super Saiyan 2 and fighting Cell. That kind of way.
However, I argue that GT had far more highlights, far more engaging fights and far better transformation sequences for the introduction of Super Saiyan 4.

If you wanna watch Daima, you have to watch it as a different take on Dragon Ball compared to Super and GT, like adventure 'more' and that adventure being more wholesome than comedic, Super Saiyan 3 Vegeta, Demon Realm lore and want to see Super Saiyan 4 again (which you can see in GT and Heroes too but better). Don't watch the show thinking its 'canon', for the 'good' fights and comedy.
