Too much sis TIME magazine is way more prestigious than the other list. Forbes only measures money, but a real global star needs to have impact and influence. You can be a billionaire and have next to no influence on culture. An artist should always prefer to make TIME magazine.
No, Forbes measures impact as well, which is why the split their sections up into 4 different categories.
TIME handpicks people they THINK are influential, clearly Forbes bases on crunching numbers.
