I just got my HERO10 Black and the out of the box performance is way better than my HERO9 Black which I love. The touchscreen is very responsive and easy to navigate, and I really like the quality of the screenshots from my 4K recording. I know it can go up to 5.3K, but most of the time I'm at 4K/30 or 4K/60, which also improves battery life in the field. The lens also looks different and stayed dry in the pool as soon as it came out of the water. Not sure if it's the same as HERO9 but seems different and better. Works with HERO9's dive housing and battery, so it's fine there too. So far, so good!
