The normal UV one is just a plain piece of glass and the coated one has an extra layer of coating of reduce flares.
The HMC ones (High Multi-Coated) are of cos more expensive as they employ more layers of coatings to improve image quality and further reduce flares.
Of cos better if have the HMC one but some like myself have just a normal coated one is enough. It depends on the individual.
Buy the best filter you can afford. HMC or even S-HMC.
Why? Because once screwed on, it forms part of your optical system, and any system is only as good as its weakest link.

to really understand and see the difference. go to CP, ask any of the sales staff to show u the diff between a multi coated filter(b+w mrc or hoya hmc,shmc) and a normal uv. the difference is immediately noticeable on the spot.
in short, basically when u look thru a multi coated(those really good ones) u r like looking thru air. super clear(of cos subject to the state of the filter,i am comparing brand new ones taken from box with no fingerprints etc). when u look thru the cheap uv filters, u see some "reflection" and these i was told may cause flares.
also, digital cameras are designed for the light(RGB) to reach ur sensor at the same spot. the quality of ur filter will determine if any of the individual streams of light get refracted. if they are refracted, they may not hit the same spot, hence image suffers.
thats the little that i know, may or may not be correct
Found this link to download Hoya catalog. Has all the information about the diff kind of filters they make in the pdf file. Click on the pdf link to download the catalog (Hoya PDF 1.7 MB)

But there's always a catch -> Quality
With B+W you can be assured that the piece of glass infront of your lens does not interfere with the photos you take. Just take a look around how many experienced photographers use B+W ...

I owned 2 types of filters before. If you have cleaned the B+W, it is much smoother to clean when using the lens tissue. The HMC tends to add a bit more friction. You have to test it out then you know the difference.
Having about half my lenses on B+W MRC filters and the other half on Hoya HMCs, I can safely say that, given the chance, I would have bought B+W filters from the start. They are so much easier to maintain due to the coating they use (which according to the website repells stuff, sorta like rainX that is used on car windshields).
My B+W filters can usually be cleaned with just a blower while the same sorta dirt on the Hoyas would required a lens cloth. Stuff like fingerprints on the B+Ws can simply be wiped off with a lens cloth while on the Hoya, it would require some cleaning solution (Eclipse) and lens tissues (pec pads) to rub off.. and the problem with Hoyas is that they will streak when u use cleaning solutions so it's quite a bit of work to get the filter spotless.

Eh... The purpose of a filter is to protect the lens elements and not cause too much light interference when taking the shot. my personal belief is not to use any filter at all as the filter size of the lower end ones are normally much smaller than those of the better ones (they would be bigger as they need a bigger size to allow more light in)
Thus my comment on not using any.
Cheers,
