I've tested every system I could possibly find (and am constantly on the lookout for the next best thing to aggregate and streamline all of my social media management) and so far, the best thing out there right now is Sprout Social. It's super reliable which is # 1 for me, and has the most integrations. The reporting feature is also top notch. Stephanie who works with me actually did a really good post comparing Sprout Social with Hootsuite which you should check out: http://www.neworleanssocialmediaconsulting.com/sprout-social-vs-hootsuite/
