The thing you gotta keep in mind about the two is that Kishimoto was able to finish Naruto on his own terms. He decided how he wanted to resolve the final conflict, give closure for the big players in the story, and he followed through with that plan. Was it perfect? Hardly. It still had some holes and some things weren’t explained as well as they could’ve been, but it was a mostly satisfying ending.
Now then, Bleach. Bleach did not have a natural ending. Bleach was cancelled, and Kubo only had enough time to wrap up the main conflict and a little closure to a handful of characters. Yes, we saw a lot of them in these two epilogue chapters, but we don’t really know what they’re doing now. This isn’t to say I didn’t enjoy the ending, because I did, it’s just that there very clearly could’ve been a lot more to it.
That said, even if Kubo had more time to get to the ending, there’s no guarantee it would’ve been vastly better. The story had been deteriorating a lot over the last 100 or so chapters (if you ask me, it really started to go bad when Yhwach invaded the Soul King’s Palace and all the villains suddenly had absurdly stupid and powerful abilities.)
In conclusion, Naruto had a much better ending than Bleach.
