In my experience (Civ4), paratroopers were ideal for reinforcing defensive positions and cities, or for taking an empty city after it had already been bombed into submission. I never used them for real attacking.
They can't take an 'undefended' city in Civ 5 though, so that limits that.
The thing is that the alternate for them is stronger and moves 2x as far when not paradropping. It makes them exceedingly limited. Even more so since Civ 5 railroads are no longer free passes, and they cost gold to maintain, so you can't just coat your entire empire in them very easily.
