There is no definitive answer when it comes to whether or not 165Hz is better than 144Hz. Ultimately, it depends on the individual and what they are looking for in a monitor.
144Hz monitors offer smoother motion playback and faster response times which can be great for gaming. However, some people find that 165Hz monitors provide a more immersive experience with less motion blur.
If you are looking for the best possible gaming experience then a 165Hz monitor may be right for you. However, if you are mainly using your computer for other tasks such as web browsing or office work, then a 144Hz monitor may be more suitable.
