答案

Well, intelligence is the quality I would choose when I gonna choose a friend. For one, you could learn many insightful ideas when having a conversation with them. Surprisingly, you may find these words or ideas help you deal with work and life issues quite well, like how to persuade your colleagues to accept your ideas or how to vent your emotion when you feel stressful. For another, though cheerfulness and kindness are essential qualities of friends, but what they could bring u is just happiness or joy, nothing else. Not like the intelligent, they could provide u with knowledge, insights and visions, besides happiness and joy.
