I grabbed the mission 1 pro, the menu is different from their hero line up and actually smooth and usable. Not to mention the GoPro Labs QR settings that make setting up a crazy recording profile or trigger easy.

I used my friends Ace Pro 2 and the menu was great but kinda clunky compared to GoPro.

No allegiance to any brand, but the Mission series software is fast and the footage, especially slowmo, is breathtaking
