The main difference is that having a home server means You are in complete control over Your data. You can run home server and isolate it from the internet, running only on local network. Great for privacy and You are not relying on some external provider being reliable and available.
It also has it’s downsides. You have to maintain the server, keeping it up-to-date. Checking if some components need upgrading or replacing - which is mainly about having healthy drives so You do not loose all Your data.
