I don’t use ESR, but I read from buyers testimonies, the ESR is an okay paper feel screen protector and one of the popular ones aside from the original paperlike that cost almost twice.
I think for that price range many brands have the same specification and quality.
I use paper like from SwitchEasy. So far so good. Easy to install, very minimum screen quality degradation, fun to draw with apple pencil. Low paper noise when drawing / writing with pencil. No problem with finger swiping. Also so much less finger print oils compared to naked screen (which is so gross).
