How safe are covers and protective film from Huawei?

My Huawei P20 Pro cell phone will be coming soon and I wanted to ask the following: Huawei supplies from home again and again with protective covers on the new phones, there's a screen protector.

Are huawei's cases and protective films tough, or should I rather buy a panzerglasfolie and a different case?

So I have a Huawei P10 and the case that came with it was great. I used them for about half a year, until at some point they were scratched. Unfortunately, I can't say much about the protective films, as I immediately have a glass sheet attached.

- Huawei's covers are very good and also high-end.

However, you have to look if the case when the camera sticks out, like the Huawei P20 Pro, the camera protects acuh (ie goes on camera)
