I'm not a pro photographer but I do enjoy amateur stuff. In terms of the newest cameras the DSLRs have essentially no advantages and many disadvantages. The one major thing you could cite as an advantage is the quality of the picture you see when looking in the viewfinder. But for most folks that isn't enough to make up for the drawbacks of reflex cameras.

Quality isn’t overly important through the viewfinder. You’re just using it for composition.

Whereas an EVF can fairly accurately show you composition, exposure at current settings, any sort of raster graphic they want on the screen (eg the head silhouette to frame passport shots), etc.

My biggest gripe with the EVF is that it kinda sucks for astrophotography. I have to crank the ISO way up, take a test shot, and then turn it down before a long exposure. Our eyes are just much better at focusing on dim points in the sky.

Not sure what camera you use, but in Canon's terminology you can turn off exposure simulation which will make the image through the EVF look like a correctly exposed image with ISO cranked way up but you can set your shot ISO as low as you want.
