WD My Cloud home "vs" or "with" Air Port Time Capsule Apple

Dear all,
I’am thinking to get My Cloud Home as I need more space. This moment I already use Airport time capsule. Would be a good combination or a waste? Please give ur opinion… Thankyou

In which terms you want to use the My cloud home with time capsule?

Thinking of using both of them. My cloud home lan port connected to time capsule while usb port connected to mac mini.
Is this a good or bad idea? Thankyou
