What does Russian sunflower seed mayonnaise taste like compared to Hellmann's mayo?

Just curious. Is it tastier?

Re this mayo wiki

Mayonnaise is very popular in Russia where it is made with sunflower seed oil which gives it a very distinctive flavor. A 2004 study showed that Russia is the only market in Europe where more mayonnaise is sold than ketchup by volume. Leading brands are Calve (marketed by Unilever) and Sloboda (marketed by Efko). [2]

Mayonnaise has a pH between 3.8 and 4.6, making it an acidic food. There is a misconception that foods like potato salad can make a person sick if left out in the sun, due to the mayonnaise spoiling. This is false; the pH of mayonnaise prevents harmful bacteria from growing in it. Left out of refrigeration, mayonnaise will develop an unappetizing taste and smell, due to other types of bacteria and molds that can spoil it; but will not make one sick. [5]
