Udemy vs Coursera

$Udemy(UDMY.US)$ $Coursera(COUR.US)$ With Udemy recently going public, I have begun looking into both companies as potential investments in the edu-tech space. I saw that both companies have experienced good growth in the last couple years but the question is how much of this is attributable to Covid. What do you think about these two companies and which one would you consider more appealing?
