What is the best kind of friendship someone could ever have, and why?

I want a friend who connect well with me, so I can show everything in my mind to them. However, I don’t have that kind of friends yet. I have some friends whom I get along with for a long time, but I don’t feel we have great chemistry. I feel comfortable and always have a nice time with them but sometimes I notice that our values are way different and sometimes they make me feel bad. I would be rude at them sometimes, too. That’s why I can’t have a deep talk with my friends.
