Here's the rub: it's not the equipment that makes photographs, it's the photographers who make the photographs.

Yes, TechPan and other film behave differently from normal pictoral films. Figure out what they do, and know what they do, and then you can use them to their strengths. I didn't stock up on TechPan because I was enjoying large format. I have found the grain of Acros to be nearly as good as TechPan, and certaintly finer than TMax or Delta.

It really depends on what you want to do, with what, and what characteristics you want in the final image.
