Mechanical keyboards are like guitars, you can play the same notes on a cheap one as you can on something custom made for you for thousands. Do they sound very different? Almost always, although the guitar needs someone who can actually play well, unlike the mechanical keyboard.
However, if you really really care and you really really know what you want out of either you can tweak absolutely everything about both. You want ultra soft silent keyboard? Sure. You want the most clickty keyboard with tons of pressure? Sure. You want something thocky but still has lots of flex? Sure.
I use only 40% and 30% keyboards, thats ones without dedicated number or f key rows, and have done so for about six years now. Majority I use are standard stagger but a few are ortho or splits. Almost all of them that I like using are split space with left half as enter and the right as space.
I can touch type, although I am not the fastest, only a bit above 80wpm. This is mostly due to me being dyslexic so spelling is challenging for me and I can get bogged down looking up words or retyping it. If I do not give a shit about spelling I can easily get well over 100wpm.
I think the main show off skill I can do is look at a person I am talking to while typing a different conversation on the computer. Obviously I cannot do either if its complicated conversations but simple stuff is fine.
