Well, it depends on what you are used to. A frequency given to me as "twentythreeseventyfive" or compounded altimeter settings and transponder codes would make things more cumbersome for me in a high-speed, busy communication environment. I grew up with the European way of radio communication and my brain needs to "translate" the compounded information into the familiar format.
While it's not overly difficult, it adds more load, as small as that load may be.
And more load is never a good thing.
What works best for you doesn't have to cut it for everybody else. Everybody will have to adapt in some way, depending on where you fly. That should be both pilots and ATC.
