What's the difference between different switch films/stickers? Which are better?

I have found some stores with polycarbonate switch films:

https://kr.txkeyboards.com/products/switch-films
But I don't know if there is any difference in thickness?
But it is not the case of the topic. I also found some films on AliExpress which are stickers if I understood right? (my English is not the best)

There are 2 spices: single and double layer, but I don't know if the difference written by the seller is real.

I got really impressed when I saw videos with switch films, but, unfortunately, they all were made with polycarbonate films, and I haven't found anything about other films.
I am really interested if there is any difference between films and stickers (and the difference between single or double layer ones). Especially, if polycarbonate can make switch more stable than sticker.
And sound of course...

I haven’t spent much time looking at films yet so I am also interested. I’ve always wondered if an elastic material would work better, but I think films are usually hard plastic? Maybe I’m wrong about that.

I can maybe help with your questions about that listing. I am not sure what you mean by stickers, I don’t see anything about adhesive. It sounds like the main difference is just that the double is thicker, and I have no reason to believe it isn’t true. It may not actually be double thick, but I would guess it’s noticeably different. The doubles also come as individual pieces while the singles are still attached and need to be ripped apart.

Films are definitely superior to stickers IME. Switch stickers tend to be very thin & have much less of a tighten effect on the housing. Both TX & Kebo films are good quality products, TX is the thicker of the two & most considered superior. Although the thickness needed can depend on the switch you are filming TBH. For example NK Creams have fairly tight fitting housings which make Kebo films a better choice for them IME as TX films are thick enough to keep the housings from latching together properly. On the other hand you have JWK/Durock switches which have very loose fitting housings that benefits from very thick films, you use two TX films on one switch & the housing will still latch together properly. Which brings me to a third option for you Thicc films https://paper.dropbox.com/doc/THICC-Films-FZEtIWwgopvJauX0jlG3N which are even thicker than TX films. Although I'd only use them if you are using a JWK/Durock switch.
