For real. When one of my friends dropped his phone and cracked the screen ,we saved it by checking and backing up his stuff through samsung dex. Smart Switch doesn't work through dex though, so we still had to guess where the buttons were on an all white screen to work it through the phone.
I didn't realize til shopping around recently that most flagship phones' type C ports are only usb 2 instead of USB 3 like the Samsung S series phones. I reeeally wanted HDMI out in case I needed it in a pinch, too.
