Ben Simmons is a career 14% shooter on very few attempts. Simmons is Much thicker/more imposing and a very capable passer/rebounder/ball handler, but literally a non threat from the outside. You leave Egor open and he will hit a decent amount of 3s. Simmons is versatile, but Egor should shoot at least 30% from 3 and will take multiple 3s every game. Simmons rarely shoots 3s, it is not part of his game.
Not to mention, Egor is a very likable guy, unlike Simmons, which is part of the reason I can't compare them.
