I have always used Winsor & Newton so when it comes to quality I can't compare. I know this brand is considered a medium quality amung watercolor artist, but I like the result I get, so I never the felt need to change. The brands Golden and Schmincke are considered better quality, but also more expensive.

I usually by the 5ml tubes for the price of €6.

If you see the size of the tube you might think this is a lot of money, but one tube lasts me a really long time. These are watercolors, so you can keep reactivating them... and if you are like me, and never clean your palette, it will take you even longer to use up the colors.

Also ready about my Personal experience in the next tab.

Winsor & Newton also has a student quality series named 'Cotman'. These were my first watercolors. After switching to the Professional series I hardly ever used them.
Cotman colors are less vibrant and more prone to creating muddy colors when you start mixing!
