I already owned this monitor for over a year but bought it for a client so I'm aware with how this monitor is and it's my daily driver.
For gaming it's a great option for those wanting to get started with a load of features such as a 75Hz refresh rate instead of 60Hz, AMD FreeSync and 1ms response time. Many don't like a 21.5 inch panel but I quite like the size. However, if you're somebody who relies on good colour accuracy and viewing angles, I don't recommend this monitor as it is a TN panel, viewing from the sides is ok but viewing from the top can wash out the image and I've noticed some obvious banding issues unless that is just my model, but for gaming, it's a great option.
