Depends what you're using it for.

Just file storage?

Or you want to be able to pull full res videos and images on demand?

I love my Synology. I run lots of stuff on it using Docker.

I like my synology for the fact that it's so hassle free to maintain. I don't have much time (and to be able to do everything on a normal PC would take huge amounts of time), so that's what makes it a good bargain for me.
