I personnally bought a Pocket 6K Pro since a few weeks and I'm very happy with it.
I alredy have a Sony a7sIII, and wanted another camera but not another hybrid or mirrorless camera, I wanted a dedicated cinema camera. I was torn between the fx6 (cause it's the perfect match with the Sony a7sIII), and the Canon c70 (cause I liked the small form factor and everything it offers). But when making my plans and comparisons, besides AF and battery life (though it's very manageable), the pocket 6k Pro ticked all the boxes for me, my style of shooting and the projetcs I usually work on (music videos and corporate).
So as the price is lower than the two others I gave it a try (knowing that I previously owned a Pocket 4K for 5 months but I was doing mostly photo gigs at that time so I sold it but now I only shoot video).
I can't regret at all. IQ is amazing, it has that depth that lacks in my Sony a7sIII footage (thought it's really good too).
I can match the 2 cameras very easily without too much hassle, and they're very complimentary. One for more crafted visuals, more controlled shots, the other for run and gun situations, gimbal and shootings where AF is a must.
For the price, this camera is such an incredible tool to make beautiful images.
The Sony Fs7 is a workhorse, and has been since its release for a majority of filmmakers. But I think the Pocket 6K pro is more future proof, more versatile due to its small form factor and the price makes it a no brainer to me.
BUT.... It all comes down to what you shoot on a daily basis and what do you expect from the camera you plan to buy.
