Actually if you look at year 3 of each player's development, Madar looks like the superior prospect. I believe Avidja got more hype because he plays a position where he can score more - SF and he took away MVP of the FIBA U20 tournament in 19-20. BTW Yam Madar's team actually won that tournament, with him playing a pivotal role, chipping in 15.9 points 7.7 assists and 1.4 steals per game.

But Yam Madar improved on a base package that centered more on defense and playmaking at year 2, and evolved into a complete offensive player, adding scoring and outside shooting to his package and improving even more the ability to get his teammates involved in the offense by year 3, earning the Captaincy of his team.
There's no reason to think that Madar won't continue to grow in the right environment. And if you're complaining that our current point guards are too small and don't play defense, then Madar has got them beat in that department. His NBA comp is Patrick Beverly because of his pesky defense. Although Yam is bigger 6'3 180 to Beverly's 6'1 172 measurement at the NBA Combine.
Here's a video scouting report talking about Madar in year 2, talking about his strengths as a defender but his need to improve his offensive game.

scouting report talking up Madar's strengths:
"What really makes Madar a special defender is his lateral quickness. He works incredibly hard on defense and is able to fight over screens and stay in front of defenders. While he is still prone to mistakes taking risks and getting himself out of position, he is a very plus on-ball defender and a complete pest that is able to bother ball handlers with immense pressure.
Another strength of Madar is, well, his strength. As a relatively small guard at 180 pounds, you would think he would be attacked on switches. While it is not impossible that Madar gets targeted on switches with teams trying to exploit his lack of size. Madar, however, has shown that he is a physical enough defender to handle switches on to bigger players in the post."
