FWIW, it is worth considering that when someone says that digital color is better than transparency color what they are saying, if expressed a little more accurately, is that they like digital color better for some personal reason of theirs. Those reasons might not apply to you. If ultimate dynamic range and resolution are the only things that count for you, then digital with a high resolution sensor is better, for you, than slide film. If qualities outside those two quantifiable measures matter to you, then slide film might be something you would really enjoy.
I shoot both color slide film and high resolution digital color. They're different. Better DR is not the same as better photograph. Some people here have said that there is no point in shooting color transparency film any longer. That is their opinion, I just can't see it. But that's only my opinion.
It might be difficult to get a good scan of an improperly exposed transparency, but that is an exposure problem, not a scanning issue. With a properly exposed slide, it is absolutely not difficult to scan-other than the fact that good scanning is not particularly easy to begin with, for any media.
You've got a MF camera. That right there is a great reason to shoot color slides, but mostly for projection, secondarily for creating huge vibrant prints.
A 6x7 projector is hard to come by. Hasselblad PCP 80 projectors are readily available, but are not cheap. In your position, buying one of those and projecting slides cropped to 6X6 or 6X4.5 would be the best reason for shooting slides, in my book. If that is not something you want to do, you lose one of the big reasons for shooting slides, IMO. Most people who do that will tell you that viewing a digital color photo on a monitor, or a large print, is a joke compared to the visual impact of a projected medium format color slide. That is the biggest reason I shoot MF transparencies. But, it's expensive, and a little cumbersome. I can show a photo to my family on a monitor, and have them say "that's pretty", then show them the same photo a month later, projected, and the usual reaction is "oh, my God!"
Personally, I prefer the available transparency emulsions to the available C-41 emulsions, so for film I mostly gravitate to black and white and slides, but that is a color palette issue, and personal preference only. Mostly Provia for people and general work, Velvia 50 for landscapes.
I scan with a Nikon 9000 MF scanner and use Silverfast software, both the Ai scanning software, scanning with multi exposure at 64 bit RAW, and their HDR processing software. Their HDR processing of the resulting RAW scans is absolutely critical to getting the scans I am happy with. Any drawbacks to the inherent dynamic range limitations of slide films are minimized with this method. 6x7 you will end up with around a 280MB TIFF file, with which you can do almost anything. Scanning on a flatbed with Vuescan wont get you the same results. You can get extremely rich files using this method which hold up amazingly well to processing in PS, with excellent tonal range. But then, at this point you are back in the digital realm, which perhaps you don't wish to be. But, you asked for personal opinions and experiences.
So, if I had a MF film camera, I would absolutely shoot color slides.
