In a way, I agree with you that buckling spring keyboards are a novelty now but back then they were a revelation, and once you start using a keyboard with high tactile feedback and positive keyclick you won't want to go back.
I still have my Model M SSK, but these days I use a LoFree Flow84, which is a smoother, quieter experience. And it has absolutely the best space bar I've ever used on any keyboard.
I tend to err on the side of loud-click switches (Alps/Matias, buckling spring, Gateron Melodic or Kailh Box switches lately) in part because I beat a series of late-1990s dome keyboards to death because I needed some sound to feel like a key was registering.
A family member has a light linear board basically because he wanted a Pride-exploded-on-his-desktop lightshow and it's very awkward for me to use.
