Depends on the age group imo.
I think the people who experienced internet from ca. 2005-2015 will have the best English on average. Because in this time English was simply necessary to get a grip on a lot of media, games, websites... Now a lot of things are translated, sometimes by force (youtube, reddit...) and with bad auto-translation. Also German content creators became much more widespread since 2015, so now people might never need to look past their language horizon.
Of course the dates and statements aren't absolutes, just general observations.
Quran 17:44
تُسَبِّحُ لَهُ ٱلسَّمَـٰوَٰتُ ٱلسَّبْعُ وَٱلْأَرْضُ وَمَن فِيهِنَّ ۚ وَإِن مِّن شَىْءٍ إِلَّا يُسَبِّحُ بِحَمْدِهِۦ وَلَـٰكِن لَّا تَفْقَهُونَ تَسْبِيحَهُمْ ۗ إِنَّهُۥ كَانَ حَلِيمًا غَفُورًۭا
"The seven heavens, the earth, and all those in them glorify Him. There is not a single thing that does not glorify His praises—but you cannot comprehend their glorification. He is indeed Most Forbearing, All-Forgiving."
