Need some advice for the OLED 1TB

Hi, I am thinking of getting the Steam Deck OLED 1TB version. I have never owned a Steam Deck or a Switch. Just a Playstation Portable YEARS ago. I mostly game on PC but when I am traveling I'd like to continue gaming.

Do you guys use a Screen Protector? The Site I buy it from recommends me the Spigen AGL05600.
Is that any good would you recommend this one?
