they are just different things. just like a capacitor is not better or worse than a resistor. some applications will need a regular transistor and others will need a mosfet.
if I where you I would worry less about what things do, and more about what you want them to do. think of a cool project you would like to build and set about doing it. using any transistor to make a led blink is a fairly pointless exercise anyway. I dont know a whole lot about electronics either, but I have learned how to use a transistor becouse I needed a transistor.... as long as you dont need it, dont worry about it.
