The two only seem to have very briefly been brewed in parallel. By 1950 XX was gone, and Best Ale was left to fly the Mild flag alone.
The main difference between Best Ale and Whitbread's pre-war Mild (apart from the lower gravity) was the amount of crystal malt. In 1939 X Ale, over 13% of the grist was crystal malt. In 1950, it was just about half that. As is typical for mass-produced Milds of the period, the colour comes from dark No.3 invert sugar and caramel.
The grist retains the typical Whitbread simplicity: mild and crystal malt, plus No.3 invert and caramel. There were, however, two types of mild malt and two of crystal malt.
The hops were English: Mid-Kent from the 1948 and 1950 harvests, plus Essex hops from 1949.
