I think bullpups are king for the person with one rifle who doesn't know what situation they will find themselves in.
This is very true. And it is pretty impressive how people can simply adapt to what they have, even if the gun is not considered "ideal" from various perspectives. Some may argue this may be a good situation since presumably if all you have is one rifle, it will be the only thing to which you can become accustomed and familiar - that probably allows you to learn any nuances and you adapt to any perceived quirks
