I used to make prints in the wet lab many, many years ago. I never enjoyed the process - smelly, messy, takes up a lot of space, and expensive. I think today, with the advancements in inkjet technology it would be the least attractive option unless you needed to use the wet lab method for a specific set of reasons. Besides, if you are using a digital camera I'm not sure how you could easily incorporate a wet lab in the printing process. There is no physical negative to work with.
That leaves the other two options you mention. In my opinion if you really want to pursue the best quality and want to have the option of using a variety of papers and techniques then self printing is the only way to go. Costs are comparable with the commercial labs these days once you get over the initial expense of buying a printer.
