Still needed when installing Rankmath SEO?

Hello,

When installing Rankmath SEO, I see there is an option for Redirections.
Is this the same as this plugin?
Does this mean that if I install Rankmath SEO and activate Redirections from there I won’t need this plugin?

I need to redirect specific URLs of old posts that have been deleted and send them to other posts instead and wondering whether I’ll need this plugin or of I may perform this simply with Rankmath SEO.

Thanks.
