What makes an LS better than a small block?

And I'm about to make myself seem like an idiot but that's okay.

What is the difference between TBI, TPI, and EFI (Did I leave any other common ones out?)? Throttle body, tuned port, and electronic fuel injection, respectively. Which one is fuel injection directly into the cylinders? Which one is the one that pretty much looks like a carburetor?

Best option for a Gen I (taking into account total cost, gas mileage, and power)?
