Which guy is likely to be the wisest option?

I’m currently getting attention from three guys, but one has a girlfriend, so I think he doesn’t count.

Guy 1 is a model and as such, is attractive. He’s also intelligent, sensitive, selfless, down to earth and kind. He’s been chasing me for a few months. Talking three times a day. Guy 1 doesn’t have a sense of humour and gets jealous easily.

Guy 2 is a librarian. He’s not handsome, but he’s intelligent, funny and interesting. He said that his book club said his behaviour makes them feel uncomfortable.

Guy 3 is a model. He is handsome, seems kind and full of personality and seems flirty, but he’s got a girlfriend of four years, that he mentions often. He’s sung to me, expressed excitement to see me and keeps glancing at me from across the room when we’re out in groups. I tend to think the fact that he’s got a girlfriend rules him out.
