To me making a decision on 6 clear cut definitions is much more simple
than on 3 or 4 that tend to get into gray areas (although they
shouldn't)

I'm not familiar with the "6 clear cut definitions" of which you speak.
When I make go/no-go decisions, whether for IFR or VFR, there are always
gray areas. The only time the decision making is trivial is when the
weather is perfectly beautiful, or when the weather is absolutely
horrendous. There's a lot of room in between for IFR and VFR flight both.
