We use it here at SQLServerCentral. We expose the data at monitor.red-gate.com. It's delayed slightly and replicated to another server for the public side, but you can play with lots of it. We even have custom metrics, both performance and business related ones.

Monitor is built to monitor and alert. That's it's focus. Some of the other products are more for digging in and troubleshooting. It depends on what's more important to you. I'd say test them, think about what you need, and then decide.
