Hey guys, which is better, RankMath or Yoast?

I've been using the free version of rankmath after watching youtube bloggers recommend it, I want to buy a pro version to try, but the official website sells it too expensive, it costs more than 80 dollars a year, which translates to more than 500 soft sister coins a year. I also see that many people are recommending Yoast, is there a big difference between the two of them?
