If you want 4k 60p go with the pana. Anything else the Olympus at that price is a steal. If you're talking about V-log just shoot Oly's flat profile and be mindful is 8bit and not so gradable, but colors overall are beautiful. If you plan to get the look in camera you have a great deal in your hands. The only thing missing is video backup to the second card but that's personal preference. I would take it if I got an offer like this.
