I remember reading a long time ago that cultivating the four brahmaviharas leads to eons in heaven. I tried to find the sutta but couldn't.
The point is, loving-kindness led to the least eons in heaven, compassion to more eons, sympathetic joy to even more, and equanimity to still more.
So, does this mean that equanimity is considered the best brahmavihara, and the others less beneficial?
The greatest glory in living lies not in never falling, but in rising every time we fall.
