content: Cube is: - 30frames at 1080p - 4.2 ounces (~130 grams) - 120 degree angle lens    GoPro Session: - 60 frames at 1080p <-- big difference - ~70grams (twice lighter) - 170 degree wide angle view     all 3 points above are rather heavy hitters in terms of usability and applicability of the product. I can mount Session on a mini quad, record at 60 f/s and get 170 degree angle and it would look like i'm flying a big ass nitro model.   Anyway, i think the pros are obvious here.
