Hello Simtutz. It is not possible to make a general statement as to whether one of the two is more worthwhile for you, as you do not say what your requirements are. I'll make the assumption that you would like to take photos with both cameras.

The main differences between the two devices are as follows.
* Sensor resolution - Sony 24Mpx / Lumix 16.10
* Max image size - Sony 6000 x 4000px / Lumix 3840 x 2160px
* Sensor size - Sony APS-C / Lumix Micro Four Thirds (The sensor of the Sony is bigger and therefore a bit brighter).
* FPS (frames per second) - Sony 11 / Lumix 9 (especially interesting if you want to shoot series, e.g. sports shots).
* Lens Mount - Sony e-mount / Lumux Micro Four Thirds

From my own experience with the 6300, I know that the Sony has an extremely impressive autofocus. Unfortunately, I don't know whether it is as good with the Lumix.

Personally, I own several Sony systems, including the 6300, and am perfectly happy with them for both stills and video. If the resolution of the images doesn't matter to you and you're happy with anything above 1920x1080, I'd recommend the Lumix. You can certainly use the money saved later on for a second lens :)

If resolution and/or light intensity (performance in low light) is important to you, I would recommend investing a few francs more.
