we are comparing

<xsl:variable name="aDate" select="A/Date"/>
<xsl:apply-templates select="$aDate | B/Date[not($aDate/text() =  text())]/>

with

<xsl:for-each-group select="(A|B)/Date" group-by="."/>
<xsl:apply-templates select="."/>
</xsl:template>

Personally I find the latter more readable and it is a lot more efficient.
