Well I am a pro in usage of tools like Brandwatch, Websignals, Crowdtangle and many others. As a consultant I basically make decisions for customers, where to go. At this point I wouldn't go with No limits.
First, there are some strings with the limit of streams. 50.000 on Tier1 is nothing and not every customer can say how much he will need.
The number of Keywords is ridiculous. With 10-20 I wouldn't anyone recommend to go with the tool.
I use it now for testing with real data and huge accounts and this is a huge disappointment. At the moment it shows no follower growth for 6 days now, but there is. So where is the support? NONE.
The section Online Media almost only contains asian news outlets, almost none from Germany, just a few, put in by other customers. I would provide a list with more than 100 URLs but Batch upload of those is not possible,
I was put on a V5 dashboard, which is really Work in Progress, but gives you a little more features like adding news sources.
So for the moment I'll try it but if there is no significant change I'll quit soon and get my money back.
