In my opinion it is not. If you need lots of content for a bigger site that is more of an authority site, spinning articles is not a great idea because most of the time they don't make sense - aren't a great reading experience for your viewers.
And if you're making a smaller 5-page site, I still think it's best to write your own content. Or buy some PLR content and tweak it if you need help with content. Or you can outsource the writing. Whatever you choose, spinning is no good in my experience.
