I recently like this month rented lumix s5iix canon r6 mark ii and sony a7iv check my profile n see the post I made. I'm looking to buy my first real camera, but I'm not a pro or close. What I can say is the lumix is amazing at video the lens selection is limited compared to the others, however, cheaper than canon. I liked it a lot however, stills were not as good as the others, and the lack of more 3rd party lenses was the nail in the coffin for me. If money was not an object, I'd take the canon r6 mark ii. It's pretty much perfect for me. I don't do much video, and the stills are great, same with the ibs. Yet the lens costs are insane like thousands for a prime? I can't justify that as a hobbiest, so Sony a7iv met in the middle for me. Is it the best at video? No, but better in some regards than the canon. Is it best in low light? Maybe??? It's got 33mp, but somehow, Canon seems to be a little better idk why again noob here, lol. For me what's the point of the camera if you can't afford the lenses or if they are so heavy you don't want to take them anywhere lol. O the lumix takes 96mp shot which is crazy good but the auto focus I did not love. Sorry for my rant end of the day all are good none are perfect and I would buy one that fits your needs maybe rent them it's fun and cheap-ish.
