Binance is one of the best exchanges out there. A great variety of different features available with a wide range of crypto supported. It also has more advanced features for the more seasoned investors.
Although it was quite easy to buy my chosen cryptocurrency, there are aspects of the site that could be improved from a UI perspective. It can be quite daunting for new user to cryptocurrency and would take them quite awhile to understand how to navigate and likely get the information they want from the site.
I would also recommend using the app to do the initial sign up process, doing this through the website is not as easy as it was through the mobile app.
