Composer vs Custom object

Permalink
Hi all,

I'm wondering why and when use custom objects instead of using the built-in composer tool.

And so what are the pros and cons of both.

For example, creating a news system is great with composer but dealing with a lot of news with attributes can maybe be a performance flaw when searching/filtering pages due to relational queries attributes<>pages<>collection<>blocks because News are not their own objects type but are mixed with pages.

It's a big storm in my head! xD

Thanks
