I’ve been shooting with a gh5 for almost 2 years now and I love it so much. I’m a bigger fan of the micro four thirds lens selection too compared to Sony. Mft lenses are pretty damn expensive though. It has treated me super well. Some things to consider would be that in frame rates higher than 60fps on gh5, it doesn’t record audio. The a6300 is known to have maybe the best autofocus in the game, not saying the gh5 autofocus is bad but the a6300 af is better. Other than that the gh5 kinda takes the cake, but there is that price difference too
