I actually have never heard of the other types of Hirose connectors until Tuesday when someone was testing a prototype board. The biggest difference is the size of the connector. Doing a quick search online, Digi-Key provides a nice summary and comparison of the different sizes for H.FL, E.FL, U.FL, and W.FL here => [ https://www.digikey.co.uk/en/ptm/h/hirose-electric/u_fl-and-w_fl-series-connectors/tutorial ].

As a quick note, this was an adapter used for a retired GPS module that used the H.FL connector => [ https://www.sparkfun.com/products/retired/163 ].
