The S2 compared with S2+ is a little longer.
It all depends on your needs, i have several S2+ lights, the most i care about is the tint and the beam.
A regular S2+ with XML2 will do fine for me, as long as it is not cold blue (6000+ K)
The XPL-HI will have a more narrow beam and as a result will have more ‘throw’
