As far as I am concerned, an effective composition that makes a simple strong statement trumps everything regardless of the technique employed. I don't think one needs to sacrifice anything to make a strong composition. If you choose to make the whites whiter and not grayish, of course you will lose detail in those areas. But taking the whole image into consideration, it works well. If people view a snowy image as requiring more white, it is probably because they think it looks better whiter. I like all three, because they have a soft ethereal quality, and that is an artistic choice that works well in all three images. Many year ago I read somewhere that what photographers strive to achieve in their work is, "Simplicity without monotony; variety without confusion." It is a very profound observation.
BTW, is that Boston Mills cemetery? A superb rendition. I have some of the cemetery where I used multiple exposures to give a completely different look.
