I'll try.
A dry kit only introduces nitrous into the intake tract via a nozzle or plate. The extra fuel comes through the injectors by increasing the fuel pressure(extra vacuum on the fuel pressure regulator). A wet kit sends both nitrous and fuel together into the intake tract. Wet kits are often used on cars with returnless fuel systems since that is how dry kits raise the pressure. IMO, dry kits are easier to install since you don't have to tap into a fuel source. And this may cause all sorts of comments but, I think dry kits are safer since there is no chance of fuel puddling in the intake. If you have a street/strip car in the 300hp-400hp range, go with the dry kit. For a pure race car, go wet. I've heard that with a wet system you can reach higher power levels. As to which brand, it's all a matter of preference. I like NOS, 'cuz that's what I got. I haven't heard anything bad about any system on the market, so I think you can't go wrong with any of them.
