Very much depends. For raw prize money a spot in the Champion’s League is best, but the UEFA Coefficient -which is used to decide how many teams each country can send to each of the three leagues- doesn’t differentiate the leagues. You gain as many points for a win in the CL as you would for a win in the ECL.

I feel like some countries should have multiple colors. The Netherlands, for example, has a speed limit of 130 as shown here - but that’s only between 7PM and 6AM. The remaining 13 hours of high traffic the limit is 100. Speaking of a limit of 100 - which of the colors marks that particular limit? The legend should display limits as 90-99 or 91-100 to avoid confusion.
