Us system makes better use of shapes, colors, and slashes to be more explicit
US system uses a lot of text, which is unquestionably bad. Also, it uses more slashed singes, which has upsides, it is indeed more intuitive, but also downsides, it’s more cluttered.
But it doesn’t really matter because you need to learn the system in any way, there isn’t one that is just intuitively known, and you have to learn both of them. And in this case I would prefer one that is more widely adopted.
