The answer, of course, is that you no longer have as many wires on your desk and in your bag. If you need very high reliability and fidelity, like if you’re a professional gamer or something, or you know you’re in noisy or otherwise troublesome environments, by all means use wired peripherals. I also use a wired keyboard and mouse, but it’s only because my favorite keyboard and mouse aren’t wireless and I haven’t found great wireless alternatives.
i love my bt keyboard and the freedom it gives me in the flat.
Logitech's wireless is spotty on a lot of products and their G hub application is awful but I love my Logitech headset.
Apart from that it’s just amazing, better (not as flat) keys than the magic make it perfect to type on, the usb on the side makes adding a wired mouse easy (and keeps the dongle close for wireless). I ordered several when I heard they were discontinued but still in stock at my old company just in case.
