I think the exposure pickiness of slide film is a *little* exaggerated, perhaps because of specific films like Kodachrome and Velvia that are notorious for it. With lower-contrast E-6 films like Provia, the latitude is less than negative/print film, but it isn't outrageous---typical in-camera meters, in my experience, do just fine with it. I avoided shooting slides for a long time because of the fear that my exposure skills weren't up to it, and when I finally took the plunge I found that after all it wasn't a big deal in that respect.
Scanning is theoretically off-topic, so let's suppose that you wanted to *project* your film. Onto a very small screen. With light sensors in it. :-) I'm being a little silly, but that *is* basically what film scanning is...I find the convenience of having no orange mask, and not having to fiddle around with the color balance for different films, is a big win. It's obviously possible to use either type of film, finishing in the analog or d*g*t*l domains, for excellent results---people do all of these things all the time---but given my balance of time, skills, interests, and viewing criteria, I usually end up prioritizing convenience for the "finish" stages.
(I'll invest any amount of time in the "front-end" shooting and developing stages, though. Hand-coated emulsion that has to be refined on the spot from unicorn tears and coated with a yeti-hair brush onto a technetium-iridium substrate hand-harvested from comets? I'm there! :-)
