I use Zsh with the Oh My Zsh! framework, and I use a different theme depending on which subuserland I’m in, by customising ~/.zshrc. For example, I use the gentoo theme on Debian and its derivatives, agnoster on NixOS, darkblood on Arch, strug for Mageia, apple on my macOS device, aussiegeek on FreeBSD, and gallifrey on OpenBSD. Different themes helps me remember which package manager to use and which distro-specific commands will work.
I’ll send some screenshots in a bit, when I boot up my PC.
I like Zsh because of its tab completion and command history. I also quite like its plugins.
Before anyone asks, I have tried Fish before, and I prefer Zsh. I have tried configuring Bash before, and I prefer Zsh. I have played with Ksh and Tcsh on BSD, and I prefer Zsh. I used PowerShell a long time ago, and I prefer Zsh.
Well, for all of the above, I’d personally recommend using https://linuxmint.com/ to get started. I’ve always found that it’s too much work to debloat Windows, and it’s considerably less secure than Linux (normally).
Most Steam games run on Linux, but there are a few that do not. Music production could also be a bugbear, as a lot of popular software does not run. You could always try using WineHQ to run the Windows versions, however, or try a compatible alternative.
If you simply must run Windows, you have two options. Dual-booting is a good idea, as this lets you select whether you want to boot Windows or Linux when you turn on the computer. Another option is using a virtual machine; this would allow you to run Windows inside Linux. For this, I’d recommend VirtualBox to start with.
