Most people have their favorite type or even brand of glue but in reality you will probably need at least a couple of different types of glue for different applications. Super glue does work well but for a lot of plastic to plastic seams I prefer the liquid cement that was mentioned because it actually 'melts' the plastic together so you can virtually eliminate the seam. Super glue works very well for PE parts or pre-painted parts and things like that. Don't use it on windshields and the like, though, because it does tend to 'frost' the glass. A lot of people, myself included, use clear topcoat paint as an adhesive for glueing in windshields and that has worked very well for me. I also use 5-minute epoxy a lot which is a two part adhesive that you mix together. It works very well in situations where you need some time to position a part properly.
The best thing to do is just experiment and remember NO one glue is best for everything.
