POLO is mature, the price is not cheap, but it is copied too much. It's good to have a good temperament, and it's fake to have a bad temperament. . .
Puma is sporty, but the brand is not so good, cheaper and younger.
EXR is Korean, which is fashionable, but it makes people feel tasteless. After all, he is from kimchi, and he is not in the same class as the other three.
Mainly depends on age, according to age, EXR, Puma, CK, POLO.
Do you still have money, puma, EXR, CK, POLO (almost)
EXR is relatively nouveau riche, PUMA is relatively athletic, and CK is relatively low-key but comfortable and tasteful.
If you are older, you'd better have a POLO.
If I were you, I would choose CK. It's so tasty. This is a perfect brand. . I just have no money.
