The way I understand it, the Silmarillion and LotR take precedence over Unfinished Tales, because the latter is, well, unfinished. Tales in the UT come from all over Tolkien's life, and do not necessarily follow the Hobbit/LotR/Silmarillion line as far as canon goes. The Hobbit and LotR, along with the Silmarillion, are the best examples of complete work we have from Tolkien, so they are considered more accurate.
