Not that I know of, but having done darkroom printing for the first 10 years then scanning for the ten years after that to the present day, I can tell you what I think and why I scan.
I developed some nasty health problems from exposure to chemical fumes, despite having an extremely good and costly ventilation system in my darkroom. Some people are more sensitive to this than others; I've been in poor health all my life, so messing with chemicals was probably not a good idea especially since I began doing it at 15 and did it for 10 years after.
As for quality, I was very, very good in the darkroom. My prints from scans are better, but it took a few yrs practice in Photoshop to get that good, and it took the industry to get inkjet technology improved to the point where the printers could give wet-print quality.
We're there now. You do need a GOOD film scanner, not a flatbed (especially for 35mm film. Flatbeds do fine for 4x5, ok for medium format, crap for 35mm), and a good printer with archival inks like the Epson Ultrachrome inks. AND a good monitor.
Expect to spend $1000 on a monitor. Cheaper ones are not made for graphics work and even when calibrated with third-party calibrators like the Eye-One Display do not display tones and colors accurately enough to match the printer's output. Been there, done that.
I use an NEC Spectraview monitor, which self-calibrates with their sensor and software that adjusts the screen internally (cheap monitors cannot be adjusted internally so calibrators adjust your graphics card's lookup table, which lowers accuracy). I used a Spectraview 2190UXi for 4 yrs and its is getting close to the point where it cannot be calibrated anymore (screens dim as they age), so I replaced with the PA241W, which is an incredible screen.
It doesn't matter how nice you can make the image look in photoshop on the screen if your prints do not match the screen. Don't skimp on a screen! Use a cheap computer if you have to save money, but don't skimp on the screen.
Ok, upsides:
Repeatability. If you need multiple prints of an image that needed a lot of dodging and burning, making them identical is hard and takes practice to do in the darkroom. In photoshop you do the work on the file once and every print is identical!
Control: You have far more subtle control of color and tone in Photoshop compared to the darkroom, and can dodge and burn more accurately and can do it on more areas and smaller areas. Downside is, you can be obsessive/compulsive and drive yourself crazy trying for perfection that is out of the hands of mere mortals. I do that a lot.
Safety: No chemicals. No toxic fumes, no ventilation system needed, nothing soaking into your skin.
Archives: Scans give you backup copies of your film that can be copied onto multiple hard drives and stored offsite for redundent backup. If your house floods or burns down, you lose your film forever. Downside: you need to actually keep multiple copies of your files in different locations for this to work. If you keep your only digital files in your house, they suffer the same fate as the film.
Paper choices: There are more choices for inkjet, like watercolor, etching paper, RC paper, and traditional fiber paper. You can also take your files to a lab for printing on regular silver-based photo paper! Downside: Inkjets are still not as archival as silver based black and white prints but those from good printers are probably equal or better than color prints on traditional paper.
