Absolutist thinking is not good for you and I think that it often clashes with reality. The only browser on your server should be the one you need to run there. How about a server to automate some Windows GUI thing or to run mobile OS emulators like BrowserStack does? You're gonna need a GUI there because going "headless" is not always an option depending on how interesting your work is. I've also used server editions of Linux and Windows as my workstation throughout my career because they have features that I needed or just the convenience of having the same exact setup as production.
