When I was shooting just for me it was always slide. Wife, kids, friends print.
I loved shooting slide because to me it was a purer picture. While I did my own printing in B&W, never got color printing. Additive, subtractive, it was not me. When ever I sent prints out to print they came back the way the printer, or more often than not the machine saw the picture. If I was shooting existing darkness many came back mud because they though I missed something in the darkness. I didn't miss anything, print it they way I shot it and please don't correct it thank you very much was my feeling often on what might be viewed as tricky rolls.
With slides I never had that, blacks came out black, whites white. When I shot rock bands I got the exposures I expected, not blown highlights so they could print the patterns in the speakers or the curtains.
Yes, slides are more demanding with respect to getting the exposure right, but to me that's part of the fun. Oddly, I like digital for the same thing. I'm not into post processing at all. Someday I get around to converting all my RAW shots to TIFF with some good software, but for now I'm fine.
Purity of the moment, that's why I shot slides.
