Yupp the All in One SEO plugin is also a very good plugin. But in my experience I like the 'Yoast' seo plugin. Just Not because it is a famous plugin.

Just Because 'Yoast' have a great feature which is readability test, i like the feature most. And 'Yoast' seo plugin also offer a on page seo guide in every post, so it is very easy to check the list when doing onpage on every content.
