Solid rockets give a lot of thrust per pound but usually can not be turned off - start them, burn till out. Solid fuel also stores nicely without corroding the tanks or boiling off as some liquids do.
Liquid rockets allow throttling and steering, so more or less power can applied and it can more easily be aimed.
Different fuels give different results. H2O2 (hydrogen peroxide) stores fairly well and gives power when decomposed with a catalist (like for thrusters) but doesn't scale up well. Liquid oxygen gives lots of power, but is hard to store as it is very cold. Hydrogen has some interesting uses, but it is very bulky (light weight) and very cold. And so on.

well, there's solid fuel, and liquid fuel. the type of fuel used depends on what the rocket is intended for. it's basically a weight/power ratio thing.
