Yes, the shoot situation does dictate equipment used. That why I have the few AF lenses I have. I actually need to get a standard range AF but keep putting it off.

I have a tendancy to use MLU pretty much anytime I'm on a tripod. Even yesterday while shooting some 135mm and a 180mm on a tripod with speeds probably no lower than 1/500. I fugure with MLU and a remote I eliminate any chance of movement and those should get images plenty sharp for large printing. I also use a two-axis bubble level that slides into my hot shoe to level the body. This lets me frame tighter without having to leave room to rotate and crop an image to level it.

I think the fun in slowing down and really working an image is what drove me to manual focus gear a few years back. It gave me more of the feel I enjoyed shooting my MF gear. Now with the manual focus lenses and stop down metering needs with what I am shooting today, it is that same pleasant experience.
