OK, my point being that introducing a filter will always increase flare, coating or not (except for 100% ND
).

Excellent point and completely correct. Once you've decided on a filter, though, you need the best coatings available.
The coating on the front surface of a filter, when used alone, is of virtually no importance photographically; its the rear surface that is important. Also, when used without a filter, the coating on the outside surface of the front element of a lens is of almost no value. Its when you mount a filter on a lens that the coating on the outside of the front surface becomes important. Any light it reflects can be reflected by the rear surface of the filter. The less efficient the coating on the front of the lens the more important the coating on the filter.
The bottom line is that the poorer the coating on the front of the lens the more important it is that the filter be multicoated and that both the front of the lens and the rear of the filter be impeccably clean.

As long as everyone is passing on their myths and prejudices I'll throw mine in:
1) I see no sense in putting an extra glass surface in front of an expensiv e lens unless you are in blowing sand or sea spray or other hostile environments.
2) MC filters are mostly a marketing ploy and add virtually nothing.
3)MC lenses are an improvement in wide angles, zooms and other lenses with many elements; not really needed in normal lenses up to about 6 elements and in B&W photography single coated lenses are often deemed superior (that is subjective of course).
