I'd say Bluey is a better Peppa Pig. Now, hear me out -- it's surprising how many gags meant for grownups are there in Peppa Pig (e.g. "one must become one with the mud" is not humor for kids), but the art is... well, it's intentionally flat and boring. But Bluey has a lot of the same kind of humor, with visually appealing characters and world.
I think if I didn't have kids, I would like Bluey better. Likewise, I would be able to watch it without any discrimination.
