The main benefit of this tool is that it offers multiple options to test our applications, so we can select which one suits us best. We are able to use different languages and compare them with each other in order to find out what works better and what doesn't. I think there's no such thing as bad language here, everything has its place. Sometimes you feel like you're not using all available functions - but then again, maybe they have an option somewhere that would be useful for me? Maybe I haven't seen yet! But overall the product itself is very good and easy to understand. It allows us to check if our apps meet standards or even exceed them, and also helps us identify issues before releasing new versions.
