What does Buffer, Hootsuite + SocialSprout lack?

Hello,

Just working on a project. At the stage where I'm looking at social media management tools and their limitations.

What do they lack?

- For example, the social analytics on such social media management tools, I feel is a slight enhancement offered by for example Facebook (for pages)?

But I might be wrong. Any input would be great.

Thanks.

Could you be more specific what exact features you're looking for?

More social networks. They only have a couple but sometimes I need more than the usual 4
