I had Armorsuit re-applyable screen protects on my S5, S7, and Galaxy Tab along with Spigen cases. I've accidentally thrown my phone like a wild Italian speaking with his hands (I'm not Italian at all) and it landed fine 10 feet ahead of me. I've even dropped the screen on marble counter top corners without issue. The shield might be soft, but it protects well against scratches and doesn't affect the touch screen. The higher level Spigen cases are actually quite nice, too.

I'd say Otterbox is the gold standard and if you have a Galaxy S8 or 9 then it's very cheap considering what the phone is worth. I have a clear flexible thing on my Iphone which was a gift and I started dropping it the day after I put the case on so I've been lucky. Silicone is probably the way to go if you want to save money or don't want a metal case. You can even go with the leather notebook style that protects the screen but then it's even thicker and you have to open the cover and close it constantly. I've had them and enjoyed the feeling of security plus they can look nice and reflect your taste. I envy people who never drop things because they get to have a nice, sleek, thin shiny phone!
