I've also been very happy with Silverblue (an alternate flavor of Universal Blue, the same guts as Bluefin). It took a bit of an adjustment period to get used to using an immutable distro, but given that I run this as the sole OS on my daily driver, reliability is paramount. It gives the same feeling of running a highly stable OS like MacOS, but with the power, ergonomics and customizability of Linux - and anything I need that isn't easy to fit into the immutable model is just a simple Distrobox invocation away.

It's "Container-driven development" done right - containerized applications and shells _feel_ native via Distrobox (which gives them access to the host FS, network, hardware, etc by default) but without the risks of native development causing dependency conflicts. And if I screw something up, I can just spin up a new container.
