In the context of the question, I have to assume that we are talking about visual use.
In that case, it is no contest at all. I'd take the Dob all night long. I already have both a 14" SCT and a 14" Dob. They provide very different observing experiences. The C14 wins for planetary and very high magnfication, solely due to being on a tracking mount. The Dob wins for ease of setup and ease of use, and provides more flexibility for DSOs, since it can support much wider fields than the C14. My Dob is F/4.6, and with a 31 Nagler and Paracorr, it can just frame M31 and friends. That view at a dark sky site is nothing short of spectacular.
I am recently retired, and primarily an imager. My first order of astronomy business (after completing some non-astro construction projects on my property) will be to build a 20x10 observatory with two piers. One pier will hold my imaging setup, which will likely be an AP1600 mount carrying an AP130 GTX most of the time, with a bigger scope mounted for galaxy season. The other pier will be an AP1100 mount carrying the C14 for visual use.
Once the observatory is complete, I will start thinking about a new Dobsonian for visual use at star parties. My son will be taking the current 14" Dob, so I'll build a new one. It will probably be somewhere between 15" and 20". I am limited by the eyepiece height at the zenith, so it will need a fast mirror. My wife has said that I cannot build a scope where she needs to get off the ground to use it. I'll set it up with the best mirror I can source, and a Nexus DSC system for push-to (I don't need tracking for the way that I usually observe with the Dob).
