I used a fs700 a bit, most of the PC shots in this edit are fs700, the rest of the edit is mostly fs100 and any edit I made in 2012-2014 is all fs100. The fs100 and fs700 look very similar, pretty sure its the same sensor.

You choose, TBH the gh5 has 4k60 and is very small, but the fs700 has xlr, bigger batteries, and 1080p240 (gh5 has 1080p180) they are very different cameras. What exactly are you looking for? You got a good deal on a fs700 or something? Honestly, the gh5 is $2k and is completely worth it, the in camera stabilization plus 4k60 is hard to beat for skiing IMO.
