I have a EVO for my GoPro and just bought the Zhiyun crane for my GH4. I would say the build quality on each is almost the exact same, I wouldn't be surprised if they were the same company with different branding. The Zhiyun crane is awesome, I've had it for 2 weeks ish and have really enjoyed it. With a wide angle, it is so smooth and with the different setting really opens up the doors to get creative with your shots. It does have some limitations and definitely has a learning curve to really make it smooth and understand what works and doesn't but i'm happy with my purchase. It definitely has a different feel to the "glide" then the glidecam, but I think for my purposes, shooting mostly action sports, the consistency of the crane will be better than the glidecam. Although I'm interested how it will work when skiing when I need to pan up really quickly.
