2 Girls. Not sure who to pick to be my girlfriend.?

Us 3 ( 2 ladies and I ) are more like Best Friends. We hangout a lot in a group of people or sometimes by ourselves. They are both looking for a serious long relationship, so am I. I can tell they like me a lot, and they are looking for love. They are both very sweet and very smart. One of them is very cute, but I am not sure if we would have any problems if we get into a relationship. The other girl’s personality would work great if we get in a relationship, but she is kinda tall (same as my height) and not as cute as the other one. I am confused who to pick and what to do. I always went with personality first then cuteness second when it came to choosing a girl. But this time they both have wonderful personality. It’s just I am not sure if I should pick the cute one but not sure if we would have great relationship chemistry. Or pick the great relationship chemistry but not so cute.
