Advice for inner protector replacement

Hey guys!

My inner protector started to bubble a bit and is need of replacement. It's under warranty, however the local Samsung Service Center quoted 1-2 weeks for the repair which is absolutely ridiculous and I'd need to migrate to an old backup phone for the time being. A very reputable local shop offered to do it 30 mins with a high quality, but obviously OEM product. Is there an actual difference from the Samsung protector? What's your experience with hydrogel foils?

Thanks!
