Someone without any Linux experience thinks it’s all the same.
Someone with minimal experience will tell you they’re completely different.
Someone with some experience will tell you only the package manager changes.
Someone with lots of experience will tell you it’s all the same, only philosophy matters.
Any distro can be made to be the same as any other, your choice should be on the path of least resistance for you, if you need every last frame something that updates the drivers more often is preferable, otherwise you would need to update your driver’s manually, bit it’s never impossible, it’s just more hassle.
