It's definitely different environment so there are lots of small things that you have to get used to.

In all my years of using Linux I have used about every major distro there is. I still stick to the old and tried advice, if people want hassle free distro, they should use Ubuntu.

I'm not happy with snaps but that's a minor flaw. It still provides the best out of the box experience for people who just want stuff to work.

Dual-boot can be set up at the installation process automatically. Just make sure you have enough space on your NTFS for the installer to make it smaller and stay alert that you pick the correct partitioning scheme on installation "install Ubuntu alongside Windows". Steam, Nvidia drivers all just work on Ubuntu. No need to tinker.
