I prefer jaaxy it is well worth the cost mainly for getting keywords that will get you rank high like on the first page of google. You do have to write relevant content daily

Jaaxy is a keyword tool that can be used to look for good keywords to use on your site. It also lets you see how your posts are ranking within Google. Jaaxy is a great tool and offers a lot of other information, but it is separate from WA, and you have to join their site to use it.

Many people find that using the Keyword Tool here (under Tools to your left) is enough for them and don't use Jaaxy.
