I have only played my PS5 a little bit.. but thus far I am really impressed with the SSD inside the console. The PS5 boots up pretty quickly, and the menus are super sick to navigate around. Games also load pretty fast and I'm sure loading will be even more optimized in future games. The PS5 is pretty much just an improved PS4 experience all around.
The controller.. I have mixed feelings about. Not sure how much of a fan I am with the new haptic feed back and adaptive triggers. Just feels somewhat cheap. Although a few of the things the controller can do amazes me. Just not as amazing as I was imagining for the most part. Also the controller is quite heavier than the PS4 controller.. although grip wise it's an improvement.
