I think geofft's points go a long way. I think having this conversation would require a lot though - what is "Secure" what is "general purpose". Is OpenBSD even general purpose? Is the base install general purpose? What makes an OS secure? I think maybe as a "with 0 configuration to the OS/ services" OpenBSD could be a top contender. With "I have practical security challenges to solve and I'm willing to change things in this system" I might choose Linux. If I'm handing a laptop out to an employee or friend, maybe a Chromebook, or even Windows! It's a pretty nuanced discussion that I couldn't do justice to without really caring and feeling that everyone involved in the conversation is equally invested/ coming in with the right attitude, which is impossible on an internet forum.
