OT - Windows S Mode

I bought a cheap HP laptop to travel with and discovered that it comes preprogrammed with Windows S-Mode.    I guess I am a victim of my own lack of prepurchase research.

Anyway, I have learned that S Mode is supposed to enhance cyber security but will only allow apps to be installed from the Windows Store hence even things like Chrome can't be installed.   But you can exit from Windows S Mode to get all the usual stuff but once you do you can't go back.

So far, in the week or so I have had this thing, I have been content to browse with Edge and can still use my email and things from Office, which is mostly what I will do with this cheap laptop anyway.

So, do the advantages of S Mode outweigh the disadvantages?   And (advanced question I guess) why is that that if you left S Mode to use things outside of the MS universe you couldn't change your mind and go back to S Mode?  Is it a technical thing or just a marketing thing (Windows trying to morph into Apple?)
