I use live view and the articulating screen on the T6s or M3 often for product photography, namely 3D printed objects, and for casual portraiture. I also use them for videos of items being 3D printed or for blog-style video, making the articulating screen much needed. I love my 7D2 which is primarily my wildlife rig for the FPS and AF speed, but miss the touchscreen when I try to use it for product-type shooting. I'm also invested in crop glass like my Sigma 50-100mm, so I really am not looking at FF. If it's not worth the upgrade maybe I'll just hang onto the T6s, ditch the M3 and EF-M lenses, and invest in glass.
