Every new phone deserves to be protected, especially when you have an all-glass Samsung S8/S8+. I owned the much more fragile S7 Edge with its steeper curved display. There wasn’t a day where I wouldn’t have the phone in a case unless I was briefly taking it out for a cleaning. Since Samsung opted for an elegant, unique design with the S8, the display is costly to replace. I haven’t seen the official cost to repair the phone's display yet; although I’d imagine it’s more than the $250 for the S7 Edge. No case will guarantee 100% protection for your phone, but it will provide significantly more protection than no case at all.
