You can't really say which one is better. It all really depends on the application and what exactley you, yourself, want. I'm partial to Turbos. You're offered many more options, as far as performance goes, when choosing a custom turbo for your ride(ie: housing sizes, wheel trim, overall cfm ratings).
Sicminds, yes, you can run a twin-charging system, but it's fairly useless for the street and tuning would be a major pain in the a$$.

you can get more performance out of a turbo....but they also cost a few dollars more...

I want something that is fairly low maintance and cheap to maintain. It would have to be able to stand a little dust and dirt. Since I am a novice it would have to be easy to install too. But I want to beat the 94(or older) Mustang Cobra that runs around here. I plan on having the heads ported and polished, a custom cam, roller rockers, 50hp shot of juice, a diffrent TB, headers, no cat, flowmaster 40 delta . None of this is going to happen until I get the engine rebuilt though, so I got a lot of time to deside. Which would be best for my use?

both a turbo and S/c can be used at the same time but its not worth the custom making for both

If I can be beeten by a stock ricer then I don't have enough power! I would probably be satisfied if I had an R/T, but a V6 just doesn't cut it. I've got to have more power!

Actually a twin turbo system would be the best way to go. Besides issues with your ecu in the truck, one turbo for each of the three banks of cylinders off the exhaust manifold would be the most logical and efficient way to go. Not sure about one large turbo, but it can be done with a little more lag but top end hit. If I were to turbo my sixer, I would definitely look in the direction of the twins. Something with a little lag but kick up for the mid-top end range. I think I read somewhere on the board before that a twin system is in the works. I could be worng though ;)

While my daily driver is my 1990 Dakota, my weekend car is a 1987 Buick Turbo Regal, 3.8, single turbocharger, sequential fuel injection, with many etc.'s. 440 flywheel hp, high 11's-low 12's (depending on traction) in the 1/4 mile.
Turbocharging, supercharging, and nitrous all do the same basic thing--introduce more oxygen into the fuel/air mixture. A turbocharger, as you might know, runs off the exhaust, so there is little parasitic loss of generated horsepower (a little more exhaust backpressure is all). It's easy to increase or decrease boost with a turbocharger--you can bleed boost off before your wastegate solenoid or put more spring pressure on the wastegate flap. You can, however, run into turbo lag especially with a larger turbo as it takes some time to overcome the inertia of the turbine and compressor blades. Smaller turbos spin up faster than bigger turbos (less mass). Turbos require custom exhaust systems in order to get the exhaust gas to the turbocharger. Expensive.
Superchargers are belt-driven, so they are a drag on the engine and you lose some of the horsepower they generate. They come on instantly (no lag) and are easier to install than a turbocharger (no custom exhaust work required). But they are typically very expensive. Boost is relatively difficult to change as you have to remove the drive pulley from the supercharger and replace it with a larger or smaller pulley (depending on whether you want to reduce or increase boost).
Nitrous Oxide has the cheapest initial cost--somewhere under $1000 in many cases. In the long run it can be the most expensive, as you can be refilling the bottle fairly often. I've heard that in some places it's illegal to run nitrous systems on the street, although I have no firsthand experience with that, nor do I know how the police would spot you using nitrous unless you have your purge lines running out where they can see you purge. Plus your nitrous bottle can turn into a nasty little bomb if you don't maintain pressure correctly. And your engine can grenade pretty easy if the system fails to feed it nitrous when it needs it (system failure or you just run out). Technology on new nitrous systems prevents these occurences for the most part. Much more reliable than they used to be. Nitrous horsepower can be changed by changing jets in the nozzles. Fairly simple.
I like turbocharging for three reasons: One, it has less parisitic loss than supercharging. Two, there's no bottle to refill. Just step on the gas and you have boost. Three, I'm more familiar with it than I am with the other two.
For any of these systems you need to have a way to increase your fuel flow to where it matches the new oxygen flow. Most complete nitrous systems will have a way to do that. Pre-made turbo systems will too, but if you custom build a turbo setup you will have to keep the fuel needs in mind. Most store-bought superchargers should come with the stuff you need to increase fuel flow, although if you're only running 6-7 psi of boost your stock system should be adequate (I run 24psi of boost and needed a stronger fuel pump and adjustable fuel pressure regulator to do that). If you're running lots of turbo-or-supercharger boost or lots of nitrous horsepower, you have to start thinking about pistons, connecting rods, and crankshafts (not to mention torque convertors/clutches, driveshafts, and differentials) since they're not designed to take big hits of horsepower.
For a lot of people nitrous is the quickest answer. It's "on-demand" and relatively cheap and easy to install. You can put in small amounts of horsepower (25, 75, 100) up to 300 or more. But be careful with whichever you decide on. Run lean, blow up. Run rich, lose power. A scan tool that hooks to the car's computer and tells if the engine is rich or lean is a good idea. If you can't get one, an exhaust temperature guage is a good idea (hotter is leaner).

Webos,
They don't make turbo kits that are direct-fits for the Dakota...you have to find a turbo that will work with your engine and do everything custom.

I'm definitely not the one to talk to... IntenseDak39 had one on his truck. See if you can find out what he used. Otherwise, look around on maybe cardomain and see if you can find any others with turbocharged dakotas and get suggestions from them.
