As a certified member of the photography community, gear is something I think about a lot. And with mirrorless technology coming into its own, it seems like a new camera model drops every few months. And as they do, newer old models become accessible on the used market. I do more watching than buying, but I do watch.
Part of that is looking at the camera-specific threads here. What's that $6000 box do? Must be amazing. But all the camera threads are the same. Good selection of amazing stuff, and stuff that makes you cringe. Plus everything in between. Model doesn't matter. You learn nothing about a photographer from the camera she uses. And that includes anything about her camera.
Most of us shoot raw. Once you take that through post processing, the distance between the camera and the final output is vast.
Cameras are devices. Devices get old and get replaced and the new ones are generally better. But the fundamentals are the same. If you could make good shots with your old camera, a new one will probably help some. But a new camera won't let you turn bad pictures into good pictures.
I still like the camera threads. The 90D thread is my favorite. Camera threads seem to have the best mix of pictures and words. Examples and conversation. I wish that mix would extend to other parts of this forum.
