What do you like best?
We've been using Sysomos for not quite a year now, and it has been an improvement for us over some of the other tools we've tried in the past. The range of data that it provide has been invaluable for us in evaluating campaign and strategy effectiveness in social. Our clients love how granular we can get with the data, and appreciate being able to perform Share of Voice and other competitive comparisons.
What do you dislike?
The system can sometimes be a bit less than intuitive, and frequently seems to take a long time to process data and spit out results. We've also run into a few funky graphic issues when exporting reports to PDFs, but it's not clear whether the problem is with Sysomos or the fact that we're on OSX.
Also, one of the features I loved the most - the built-in screenshot tool - seems to be no longer supported for the Firefox browser. It was very handy when pulling screenshots. I miss it and hope that the extension gets fixed soon.
