Atlas is an insecure mess, not a real solution for Windows problems. Consider a Windows alternative.

Uh, no? They're absolutely not the same.
It's even end-to-end encrypted!
Vivaldi and Brave use Blink (Chromium), not WebKit
Btw FreeTube is not just available for Windows, it also works perfectly on Linux and macOS
I’m honestly even thinking to buy a €200 android device to get used to the system.
Don't do that, I can tell you from experience: Most of them suck, especially cheap Chinese ones.
The Google Pixel 7a is currently $350 and it will get cheaper when the 8a comes out. The 7a will get security updates until May 2028. If you want to get into mobile device privacy/security, a Pixel is an excellent choice. You can install an alternative operating system called GrapheneOS, it's a much more private and secure, improved version of Android. It doesn't include Google spyware and thus also improves battery life. It also extends your feature updates, by default the 7a would only get feature updates until 2026, but GrapheneOS provides Android feature updates as long as the device gets security updates. That would mean 2 additional years of Android feature updates. I highly recommend it!
Pretty reasonable
That's the way to go
