A bit skeptical. The biggest advantage for me is the burst rate and live histogram, but the newest Canon 90D, released last year, matches mirrorless FPS and also has a live histogram. The weight's advantage isn't as big of a deal as a lot of people have claimed because many of us have to deal with big lenses anyway.

The low/night light features are cool, I think, but my "mentor" who's a professional night photographer, thinks it's all a gimmick. It definitely lowers the bar for entry in this field for people who don't do a lot of night photography. The vast majority of my shots are under full sunlight or heavy stadium lights, so it's not that big of an advantage for me.

There's going to come a time where mirrorless will reach beyond what mirrors can do, but I don't think we're there yet.

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.

The real advantage of mirrorless cameras is that there are less things that can go out of alignment, for high resolution photography everything counts (before you dismiss this, look up shimming kits for medium format backs).
