Apart from being a complete IDE that anyone can hope for, it also contains some extra features which enriches it from the free/community edition. I personally used Live Dependency Validation feature which was very useful in finding the library dependency in real time during coding. Apart from these, the ease of use is by far the best advantage you can get from VS Pro 19. Even dedicated IDEs for particular languages felt lacking as compared to VS.
Additionally, VS 19 Pro edition also provides a CodeLens feature which is quite useful for reviewing your code and getting insights of your coding feature. It is quite flexible with one click web deployment and refactoring of code.
It helps in making Windows and O356 apps and many more very easily. We can access the marketplace to download extensions for VS, which I think is an awesome feature. Integration with other softwares is tricky but manageable.
Customer Support is quite good. CS executives can help you if you get stuck or don't understand how to use a feature. Bug reporting is very easy. Review collected by and hosted on G2.com.
It is sometimes slow, all these features are memory intensive and come at a dear cost of your compute power and sweet time. Some time it takes minutes to get ready and load libraries. If you are using it frequently I would suggest not to close it. Leave it in standby mode. Review collected by and hosted on G2.com.
