Any reason to upgrade stock derailleur pulleys?

Hello.

I would like to know reason behind upgrading derailleur pulley, does it worth ? I don't think about oversized/ceramic balls or over 150€, but at least better than stock pulleys ans sealed.

What's your first decent and reliable upgrade for Derailleur Pulleys set RD-RX820 - ref Y3JS98010 (12-15€)

First I am thinking about Shimano Duraace RD-R9250 ref:Y3GK98010 (25-30€) and.... be done with it. But I wonder if there are a better upgrade.

Thanks.
