One piece is good for making content always showing and not end early and solo leveling is good at showing super interesting and entertaining battles that can get the people into watching the entire series.

I agree with this, but for me in my opinion, solo leveling has made some interesting battles that have gotten the audience all wildly because when you see a op character you like, you would want to see him be the hell up and show off his skills to some pro that thinks the main character is just some regular guy. But with one piece, I like how its long because there is always content showing and not ending early so that it wont exactly disappoint people but it does get boring to watch 1000+ episodes on one anime when you could also watch some other anime that could get even more interesting in your liking.
