That Canon has far more features than I'd expect for a DSLR - thanks for sharing.
I'm also impressed by the 90D's Handheld Night Shot mode, where it can stitch a burst of shots together like my Pixel phone.
I find that mirrorless offers another advantage from its somewhat decreased weight (a result of mirrorless camera's decreased flange distance [1], for the curious): it's relatively easy to mount most DSLR-designed lenses to any mirrorless with inexpensive adapters.
