At present, the four most common axes on the market are green axis, black axis, tea axis and red axis.
The black axis is the strongest and has no sense of paragraph. Straight up and down is more suitable for racing or games like cs.
The green axis has a strong sense of paragraph, that is, it obviously has a sense of "jam", which is generally suitable for typing.
The tea shaft also has a sense of segment, but it is not as strong as the green shaft, because it feels smoother than the green shaft, so although the same spring force is used, it always feels a little stronger than the green shaft in actual use.
The red axis is the axis with the least vertical force among these axes. Like the black axis, it has no sense of paragraph, but its force is lighter than that of the black axis, which is more suitable for typing for a long time. This is my personal feeling, but it doesn't mean that it can't be used in games.
The best way is that you can try a physical store that sells keyboards, which can best reflect your personal feelings.
