Playing Against Defenders

Hey guys, i think you're really good and i would like to be that good, but i have a question. If i'm playing someone defensive and their good at returning smashes, should i put lots of topspin on the ball or just put a lot of power in my smash? I usually try to change it up from a smash to a backspin approach, are there any better tactics?

Thanks a lot for your help:)
