I have been diving since I was 14 (back when getting certified that young was relatively rare) and due to the fact that no one in my family dives, I have been put into a large number of different buddy situations. Some buddies have been very good and some very bad. Overall I would rather dive solo than with a buddy I don't know.
I am not sure why some people are so opposed to experienced divers going solo. Well I guess I understand from the point of view of the industry since it creates new customers and shifts some liability from them to the buddy.
Is solo diving more risky than buddy diving, maybe but for me it is worth the risk.
