Mapbox

Like all the map products it works well if you have less than 100M data points - once you get over that number things get tricky and you have to make some tradeoffs on granularity and data density.

For services that require maps and basic geo-functionality in production, Mapbox is one of the greatest choices out there. They're free, provide much more refined/modern productions compared to Google maps, and have very good support on different platforms. For services that require higher-computation products, like matrix routing, optimization, etc..., the prices can get quite high very quickly, and you should consider moving those services to an on-premise server at that point.

Mapbox is great if you have a BI or Data Visualization problem while working with either large datasets or you want a high level of control on the design of your geospatial data. Also fantastic options for integrating maps onto your website or into your Android or iOS app. Basically, if you need a map in any shape, way, or form and you want a lot of detailed control over it, Mapbox is the way to go.

If you have to create specific maps that cater for very specific style, color, font and similar layout requirements this is a useful tool. The opportunity to import your dataset from latitude and longitude information, see those on your created map, and add or edit the data set including attributes is a great plus.

Beginners can start making simple maps very quickly. Mapbox Studio makes getting started very easy.

For complicated maps, one should consider the cost of hosting it on the Mapbox server. Using the API might make more sense in that case, but it requires learning how to code with Javascript.

Essential for dynamic web-maps and visualizations; less appropriate for maps requiring custom dynamically served background tiles.
