Every version of Lineage has rooted ADB accessible in the developer options. If you want root for apps, you must load Magisk. If root is important to you, this is your OS.

Lineage puts out all the patches that they can, every month, unlike OEMs. If current patches are important to you, this is your OS.

Lineage allows you to run it without any Google closed source code.

These are some serious advantages, depending upon what you are trying to do.
