I'm certainly no dev-ops guy and containers are not often on the radar for me currently so when I want a stable platform to prototype a web app on or to deploy to without fuss then Ubuntu is where I end up. Sure there may be other distros with a smaller footprint, or tighter security model, but my days of wrestling Makefiles is long gone so apt is about as deep as I go unless pushed. Ubuntu has the foundations of what I typically need out of the box.
