Comment on Stallion WordPress SEO Theme by SEO Dave.
If you are using my latest theme, Stallion Responsive 8.* it doesn’t need any SEO Plugins, the important SEO features and many, many more SEO features are included so if you ran Stallion Responsive and Yoast or All in One you’d be replicating features for no gain.
Stallion Responsive is years ahead of the SEO plugins in SEO features, in comparison the SEO plugins are a joke compared to Stallion.
Basically install Stallion Responsive and dump Yoast and all In One SEO.
