GFW is an an incredible data analysis and visualization tool with tons of different geospatial layers integrated into it (e.g., those from U Maryland's GLAD lab, WRI's Land & Carbon Lab, etc.). I also highly recommend the API, which is helpful for directly querying information. GFW is unique in that the platform and majority of layers are CC-BY, so they are open for any usage (with attribution) which expands the pool of folks who can use it. 

The platform itself is easy to use and has a lot of helpful auto-generated graphics alongside the map viewer. Great for general data exploration but also can be used easily in more complex analytical workflows. The time series of many of the layers is also great, so that you can get historical perspectives and see change over time. One of the best open geospatial tools out there!  

Global Forest Watch offers a variety of well-documented datasets (for example, deforestation alerts), a user-friendly interactive mapping tool, and the ability to produce customizable reports. The tool is a go-to resource for rapid assessments. However, it may produce inaccurate results over large areas at times, so ensure you refresh the dashboard frequently to update it with the correct statistics. I would definitely recommend it to anyone looking to explore various datasets and gain quick results.
