My decision is based on the same reason that I processed all of my own colour film and prints for my professional work going back into the mid 80's - - - I loved the process of print making and needed control of that process to get what I wanted. I used pro labs from time to time when things were really really busy and I needed to get work out - but would always be disappointed even when I gave them specific instructions or payed for expensive custom prints (some labs were $50 for an 8x10).
Same with my modern day printing - except for very large prints that I can't handle with my equipment, or when I am so busy and have to get prints out - - - I far prefer to print my own work. I don't use 10 to 12 ink printers, I use 6 ink Epson printers, and the image quality is indistinguishable from wet process printing - and the produced image is always superior because it is exactly the way that I want it. I have use both pigment ink printers as well as Epson 1400 and Artisan 800 Claria dye ink printers for my professional work. I've been printing my work digitally since 2002 after giving up my darkroom in favour of film scanners and then digital capture in 2004 and Epson printers.
As far as longevity goes - - - I have a set of a dozen 4x6 prints that I produced on my portable Epson PictureMate that uses pigment inks. since I printed them in 2007, they have been in the front window of my van fully exposed to strong sunlight as well as extreme heat and cold. They still look great. I'm sure that if I had a duplicate set stored away and compared, there would be some degrading - but I really expected they would be faded rightout way before now.
By comparison - many years ago I had a couple of large pro lab produced C prints displayed in Main Street windows with direct sunlight most of the day, where there was noticable facing after 6 months and the prints looked disgusting after a year and had to be taken down and thrown out.
Top Art Galleries accept inkjet prints. I remember reading about Graham Nash producing his inkjet exhibition prints, and has been printing digitally from as long ago as 1989 apparently ( NASH EDITIONS - The Digital Journalist
