I'm not particularly fanatical about Tolkien, but we have the one volume edition illustrated by Alan Lee, because it is lovely to read. My copy of the original Unwin three volume hardback is the unrevised first edition (though the umpteenth impression.) For various reasons, I actually prefer this version (mainly because there is a hint of a sense of humour - and exasperation - in the version of Aragorn in the heaviest changed passage) but inamac has the three volume second (revised) edition still in its DJ. So we have reasons for keeping all three...
