This is basically who is the least evil company towards their foreign idols.
For me:
Idk who is the best between jyp and hybe tbh. But I like how hybe give kazuha and hanni the same opportunity for cfs and brand deals with the other Korean members. If I remember correctly, they even the first to have solo activities in their group (except sakura & chaewon). For jyp, they are known to be the best in treating their foreign idols among the big 3 before this. I don’t really remember they have any big issues too with their foreign idols.
Next is yg. Lisa is their first foreigners in yg. Are they treating her the best? Of course not but at least she was giving lots of solo schedules and even become a judges in popular survival show in China that increase her popularity there. The bare minimum I know and she still facing huge discrimination, but who no one can win over sm for this topic.
The worst out of the worst is obviously sm. No words needed.
