The type of camera used would depend a lot on someone's style.
You're right there, IMHO. I think the question of equipment choice is so tied in to your personal style that there's no useful answer to the question, "What's the best camera for [insert a genre here]."
Whatever your photographic pursuits, whether they fit into a neat description or not, what you want is different than what anyone else wants, and what you must do to get what you want is different from what anyone else does.
The bad news is that no one can tell you the perfect instrument for you to achieve your photographic goals from a pigeon-hole description of those goals. The good news is that your photography will tell you how to formulate a question which has an answer that moves you along your path in a productive direction.
The first step towards equipment selection is the same as the first step towards almost any photographic goal: make pictures. Pick up whatever gear seems right to you and use it as best you can. It may seem awkward for the task, but ignore that for a while. After a while, you’ll notice that you aren’t learning as fast as you did. Sit down and make a list of what you’d like your equipment to do for this project, and what your current equipment does that doesn’t work for this project (It doesn’t feel like a project yet — then maybe you need to keep working a while longer). Now, armed with your list, if you want other people’s opinion, ask around for recommendations for equipment. It’s quite likely that you’ll look at your list and you’ll know what you need to use in the next phase of your project.
The shoot-analyze-buy cycle can, like the cycle on the shampoo bottle, be repeated indefinitely. There is no danger that it will converge, because your vision for the project will change as you work on it, and the universe of available equipment will change as well. Be careful about blaming your equipment for your failures in vision and attempting to buy artistic inspiration, but accept the fact that your experience with new gear will give you insights you wouldn’t have gotten with your old stuff. And yes, there are snares: we've all fallen into to "If I had x, my photography would be so much better" trap.
I've gone through one body of my work and paid attention to how changes in my vision caused changes in my equipment. It's too long to post here, but you can see it on my blog
And one last good/bad point. It's bad news that no camera is perfect for any particular task, and it's good news that there are usually several that are perfectly adequate.
