Using these official SEO tools will be much better than using paid SEO tools.Also there is no side effects by using these tools, on other side bad SEO tactics may work on a negative manner.

I agree paid SEO services also harm the reputation and ranking on search engines and Click rate, so these tools are better then a paid SEO service. Paid SEO is only good when they are trusted and having a good review among their customers so watch out before getting a paid SEO service.
