hmmm; if a filter attracts dirt like a magnet than so will the front element of the lens. They are a pain to clean, but no more than cleaning the front element of a lens, and when you've done it once too often you can replace the filter as opposed to replacing the front element of the lens

.
A decent coated filter makes little or no difference to image quality most of the time especially when used with a lens hood. For the very few times when it is a problem it can be removed.
A filter probably won't be of much use if you drop the camera, whereas a hood might absorb some of the impact.
It all comes down to personal choice based on personal experience, and a lot will depend on how and where you use your camera.
Safe advice while building up that personal experience might be to try using one for a while and see if or how much grime accumulates. If none does than you should be fine without using one; but if it does becomes dirty be glad it was there and not on the surface of the more expensive lens.
BTW, for filter cleaning (or lenses if you have to) I have yet to find anything better than opti-clean.
