To be completely honest I have went and installed couple of Samsung replacement apps even though they were not on my device by default. Samsung's email application is simply miles better than GMail, and more to the point doesn't suffer from known issue like not downloading attachments. Same with notes and similar. Especially on Fold where screen is significantly bigger, default Google stuff simply can't handle it. It looks stretched while Samsung offers better experience.

That said very few duplicates and those that you don't need you can uninstall. It's not that big of a deal.
