Amazing camera.
First of all, it is natural that you can find better cameras than this one. However, what you probably can't find is a better camera in this combination of dimensions and money. It is a miniature camera with an OLED electronic viewfinder (this distinguishes it mainly from its predecessor, the Panasonic G100, which had an LCD viewfinder).
This camera was not so popular because it competed in a category where other notable options were available (e.g. Olympus OM-D M10 IV), which excels in certain aspects, the most characteristic of which is the presence of in-body stabilization (IBIS). But what unfairly disadvantaged it the most is that it was launched as a vlog camera even though its 4K, for example, does not come from sampling the entire sensor, while its strong point is not video but photography: It is a very good camera for travel photography. If you combine it with a stabilized lens, you won't miss IBIS, and if you combine it with most primes, you may miss it.
Its flash is weak, but it has a hot shoe for attaching an external flash.
Its menu is amazing. Well organized with color codes, much better than the chaotic Olympus menu.
Of course, being an m43 camera, its small size will perfectly match the wide variety of small lenses that the m43-mount offers, and you can carry several in a small bag.
Update 15/7/2024: When taking photos in semi-automatic P mode, the camera tends to choose unusually small apertures (e.g. f13 or f11) even if the scene does not require a large depth of field, while it could choose f9 or f8 and higher shutter speeds. This results in a certain degree of image quality reduction due to diffraction. In the m43 system, f8 is a limit beyond which diffraction usually appears, although an inexperienced user may not easily notice it. Therefore, it is possibly better to prefer the A program (Aperture priority) instead of P in order to avoid this phenomenon.
I have no opinion on long-term durability, time will tell.
