It's not about the installer (who even uses those anymore?), it's about features and power.

Linux has had a lot of work done to support complex features and scaling in a number of aspects, whereas OpenBSD has not. In fact, the insistence on security and keeping things conceptually simple, almost inevitably means they pass on some significant improvements. When you want pure power, OpenBSD is just not the best choice, for example; and the virtualization stack is very primitive.
