There Are Pandas, and Then There Are Pandas.
And this isn't either of them! The Pandas we're talking about here, are watches, not bears. And what got me thinking about them (again) was a link posted this morning by @cm.rook who pointed a few of us to the very attractive (and not terribly priced) Yema "Rallygraph" Panda which, in it's most traditional arrangement, looks like the one on the left, but can also be had in the version on the right: The model on the left is a true Panda, while the model on the right is called a reverse Panda. The reason for that distinction is clear--Panda bears, only come in the first arrangement. Now at this point, everyone should be thinking about the most well-know Panda, The Rolex Panda, which is actually a Daytona, and among Rolex Daytonas, the most famous of which is the Paul Newman Daytona, which was famous first, because it was Paul's, and second because it sold at auction for $17.8 million (US Dollars). The story of that auction is well-known so I'll only...

Do I recommend this camera for pictures as in your case? Well the auto focus is pretty quick and accurate and if you're seeking a telephoto type image, you get double "zoom" (thanks to its crop factor of approx. 2). If you're going to be taking mostly wide angle pictures, Panasonic offers some reasonable priced primes which are fast as hell and will do the job. If you're going to need wide zooms, the only ones Panasonic makes are their kit lenses which frankly speaking are decent, but they really won't compete with the vast array of lenses of different focal lengths of Sony's arsenal of compatible lenses.
Have I been talking only about the G7? Yes, and I was considering one of those two cameras (those exact two) just like you are right now back when I was deciding to get a camera. My choosing of the G7? Well I wanted a solid video camera, which in terms of video the G7 is definitely better than the a6000. The G7 also had a microphone jack, and the screen was flip out as well.
In terms of pictures, it's pretty 50/50. The Panasonic has great low light, fast auto focus, an extremely accurate viewfinder, and has tons of shooting modes than many professionals can even take advantage of. The bad side? Lack of in camera stabilization, MFT sensor (depends on your use case), and not as many lenses. I have a friend who owns the Sony a6000 with the 16-50mm lens and both cameras are great. The G7 seems to be more bang for the buck in my opinion and has more features, but again, this all depends on your use case. Sony has a reputation for having great auto focus so that could be a big factor for you as well. Go with your gut. Either way, you're not gonna have a bad camera for sure.
For photos, 15mp is fine for industry standards. Personal use, anything above 15mp is more than ample. More resolution/pixels will indeed make your photos appear sharper, same accordance with video like 4K and nice to have and futureproof yourself but camera tech is advancing fast so things can kinda become obsolete quick.
4K is pretty much there to future proof your stuff in the industry. If for personal, use you may not ever need that much, nice to have but edting/recording in 4K is a little more demanding. One example is space, you'll need a fuck load of space. High end quality files in photos will be the same but will have more freedom of space. For myself, I wouldn't ever need to touch 4K for video, 1440 or 1080 is pretty much my baseline. Unless I do a project that I know I'll need 4K to get desirable high resolution. I do photo more than video and personally find higher photo mp is the better end outcome over video resolution. And since you said you're taking photos mainly, I would say the a6000 is the better choice for you. You can't go wrong on either because in the end, whichever you excel more in, you'll end up wanting to invest in a better system/camera.
I know you want to make the right choice but there isn't exactly the right choice here as both are fine options, it's just whats more appropriate for your needs which I believe is the a6000 reading from your first post.
The a6000 has 24 MP which frankly speaking, megapixels after a certain point doesn't really matter to sharpness. Like Vira said, the sharpness of an image comes down to the type of lens you use. With 24 MP as compared to the 16 MP of the G7, you're not going to be able to tell much of a difference with the naked eye. Now, if you are going to be zooming in and cropping in to your pictures, then go for the a6000, because then you have more pixels to zoom in clearly on as compared to the G7, but for sharpness, the fact that the a6000 has an APS-C sensor, you will be getting a very solid picture. Take a look at a cellphone for example. The iPhone 7 is capable of producing pictures at 12 MP. Compare that to a DSLR which is taking pictures at 36 MP. To the naked eye, (hypothetically if all given circumstances were the same) when you compared the two pictures, in terms of quality you won't see a huge difference. But when you zoom in, the DSLR will stay much sharper as compared to the iPhone as you keep zooming in. Same works for printing pictures as well. If you are going to be printing your pictures on a larger paper, finer details are easier to see so your best bet for an instant like that is to go for the a6000.
Boil it down to your needs. Do you need more room to play with cropping and printing size and zooming? Then I'd go for the a6000. Do you need clean, crispy video which you plan on viewing on a large screen? Then I'd go for the G7. Also, if you plan on recording 4K, be prepared to spend some hefty amount of money for a fast, large SD card, because 4K @ 100 mbps is not a small file size...
Adding to his comment about storage, with today's MP, you'll defo need a decent file storage regardless. MPs and Vid Reso are growing at a fast rate. Phones never been commercially capable at getting photos like you see now, compared roughly to a decade back. This includes cameras, 100+ MPs are looming about, 12K+ video, and its all still advancing. Make sure you get a good quality one, last thing you'd want is it dying on you, taking all your photos and videos with it. I know from experience, it'll hit you when you'll least expect it.
