The SMC coating is pretty darn durable and will stand up to proper cleaning probably better than any but the most expensive filter. A lens hood actually blocks a lot of pollutants too because the lens is recessed. About the only two filters for a dSLR that cannot be easily duplicated in software are polarizers or neutral density. Putting an extra layer of unnecessary glass in front of your lens will always degrade your image some as the light will bounce around between the filter and the lens. Really good filters are of course better than cheaper filters, but it is still there, and really good filters are not inexpensive. Proper sized hoods on the other hand never degrade your image - in most cases they improve it - and with few exceptions offer as much if not more front element lens protection.

You don't want a UV filter on your lenses anyhow. Hoods, yes, UV no. Hoods offer more physical protection than UV filters and actually do something to improve your photos. Your digital camera already has a UV (and IR) filter applied directly to the sensor. Adding another optical surface will only degrade your image.
