What do you like best?
as far as an analytics platform goes, it is okay. it does compile your data, but can often be sloppy, and its effectiveness depends on your ability to integrate it properly
What do you dislike?
compared to google analytics it really falls short in its ability to measure user engagement on your site. Also, it has fairly rigid implementation standards, and a small problem with set-up causes drastic problems in its effectiveness. Also, unless you are using a tag manager software, you can cause serious damage to your SEO by relying on the cm_mmc tags, since you will effectively be creating duplicates of your pages with new urls every time you incorporate a new tag. It is not for beginners, but a good enterprise integration might be okay.
Recommendations to others considering the product
be very careful with implementation, and do not allow pages to be tagged without a tag management software. Or, just switch to the enterprise google suite, save money, and get a better product.
What business problems are you solving with the product? What benefits have you realized?
I would say that because of the difficulty in implementation, it caused more problems than it solved. We switched to google a few years back and not only got a less expensive product, but one that allowed us a better understanding of our metrics, and a more accurate recording of those metrics.
