Well, I may be qualified to answer this question. I run a custom printing and processing lab. I print both black and white darkroom prints as well as scan negatives and print inkjets. On the darkroom side, I use excellent Schneider APO enlarging lenses and an Ilford Multigrade 500 system. For digital, I use the Hasselblad X5 and an Epson 9900. These are all more or less state of the art options for their respective formats.
As with so many things in life, the answer is "it depends". If you have a good negative and you want to make a reasonable sized print, the traditional darkroom will usually give you a superior image with tones and depth that are very difficult to reproduce digitally.
Using a color managed workflow (even for B&W), and high end papers like Harman Gloss Fb AL (now Harman by Hahnemuhle Gloss Baryta), digital can now get vanishingly close to a good darkroom print...better in some ways, worse in others. They are generally better in sharpness and often even dmax now, but worse in terms of tonal smoothness and depth of image. Digital still can feel like it is on top of the paper, while film feels like it is IN the paper. It feels like that because that is the case!!
Digital will surge ahead if you are printing very large. It is very difficult to make very large darkroom prints (larger than 30x40 inches say) with the same quality that it is possible to do with digital. Getting an enlarger aligned that perfectly, keeping the negative, paper and everything else flat and still for the duration of the exposure, handling the sheets of that size...it is all difficult to do without highly specialized equipment and at least one helper. Even then, you are pushing the limits and will often find that you cannot get the same edge to edge sharpness possible in a digital print of the same size. Of course, digital can present its own problems, but for the ease and precision that a printer like the 9900 and its bigger cousins can churn out huge prints, there are very very few people left doing mural sized darkroom prints. Good scanners can produce a grain sharp image of the film corner to corner which can then be translated into a huge inkjet or digital c-print.
Generally for black and white I would recommend printing wet up to 20x24 inches (50x60cm), and then go for a scan for anything larger. Exceptions would also be if you have a poor or damaged negative -- again the flexibility of digital wins the day in this case -- the power of photoshop can retouch or edit with a precision and authority that it is nearly impossible to replicate in the darkroom.
For color, I would recommend sticking to what each was originally designed for. Slides are amazing, but since it is hard to find anyone doing ilfochrome or dye transfer anymore, it is best to either project them or scan. As wonderful as the colors are in a slide, digital would be my choice for color in most situations since you are going to have to digitize the file anyway these days if you want to print and digital has much higher dynamic range. Scanning a slide works, but it is a heartbreaking experience as you try to cram an incredible range of natural colors with extremely nuanced micro-contrast into a comparatively miniscule "color-space". Slides deserve to be enjoyed on the light box or the wall.
Color negative is great for making color prints with an enlarger, but would not be my choice for digital prints. It has much higher grain and lower color fidelity than digital, and you are introducing a lot of the downsides of film (dust, scratches, expense, extra time) without many of the advantages. So. For color I would say stick mostly with digital unless you intend to be in a color darkroom or leading slide shows.
All this is just general advice. Personally I shoot both film and digital, about 50/50 for each. I shoot everything...black and white, slides and some color neg. Everything from 35mm to 4x5. But for practicality's sake, I would say stick to digital for most color and black and white film for black and white (printing analog if you can, but not discounting digital printing if you know what you are doing and make good equipment choices).
