The JAWARA data production is divided into several streams, like other reanalysis products. The data in the overlapping period are consistent within the uncertainty. However, it would be better to use the stream that goes through enough calculation period (i.e., stream 2 after Dec 2009 and stream 3 after Dec 2014, allowing 1 year spin-up), unless there are other specific requirements. Streams 3.1 and 3.2 correspond to the version update of the assimilated observation and there is no overlap.
