They are different products in the same way that Decades SDX is different from the Death & Darkness SDX. They have many instruments in common, but they’re played in different ways and with different tools. The percussion libraries share a few groups of instruments, but the composition is different (e.g. three congas in one, two in the other), and they have a few unique articulations each (for instance, the cajon is played with hands and brushes in one, but only hands in the other).
Latin Cuban Percussion EZX works better with the Latin Percussion MIDI than the other way around, but the MIDI in both libraries was created to make use of its specific set of instruments. If you have both libraries, why not use them both? Not every band gets to have two percussion sections in their songs..!
