OTA update setting: with or without recovery update?

Hello,
which is the right OTA update setting: with or without recovery update?

I have two /e/OS devices, one has recovery update setting ON, the other setting is OFF.
Which is preferred setting?

Regain your privacy! Adopt /e/OS the deGoogled mobile OS and online services

if you want to keep TWRP or OrangeFox, you have to set it OFF

ok, and which advantage do I have if this is set to ON?
What is the standard setting?

recovery manager will be overwrited by /e/ before any system update

ok, but I have seen that it’s not possible to deactivate recovery updates at Edge 30.
Is here any reason for this?
