The principle of vertical and horizontal code input method is to type with ordinary keyboard, which requires a lot of memory. Generally, roots can reach the average level of 100 to 140 through six months of correct contact, and can reach above 170 through hard work, but they still can't keep up with the speed of people talking at the same time.
So it depends on what you want to type. If you want to type synchronously, you must choose Yahweh input method, because neither vertical code nor horizontal code can reach that speed, but if you just want to improve the typing speed, you can choose either one.
I prefer Yahweh input method, because I want to input synchronously, but I'd better not teach myself Yahweh. Once you take a detour, it's hard to change. Now I want to sign up for a training course to study Yahweh, but the tuition is very expensive. The tuition fee for that Yahweh plane alone is more than two or three thousand yuan, but it's good once you learn it.
This is my personal opinion, I hope I can help you.
