Here are the best emulators for any system (well the most popular systems at least)!
At least according to me.

A solid wrapper around macOS's built-in QEMU (and Apple Virtualization). Fewer bells and whistles than the commercial options. You have to install guest tools for host integration yourself, but it uses SPICE and VirtFS, so most Linux guests can just use their own package manager.
Emulating different hardware just works. It's a lot slower than matching the real hardware, of course, but I've had no trouble setting up and running x86_64 Linux guests on an M3.
Running Fedora and Ubuntu 22.04 smooth as butter on an M1 Macbook, free and open source.
The Idea of running KVM/QEMU on iOS is beautiful. Dont know the use case for me, but I see someone running a couple of iPad Pros like "blades" in a rack somewhere, haha.
