So, let's compare the Skyray to the Hydra.  
- Except for the AAA battery (something that would seem to be outside Tau thinking for support units), deployment is essentially identical.  
- While the true range of a Skyray is more than 50% greater, that's due to the 15cm range increments that E:A uses, so the effective increase is right about 50%.  (in 40k, 45cm=48", 75cm=72" -> ~50% increase in range)
- They have equal AA to-hit numbers (both 2x AA5+).
- Given the apparent acceptance of the SMS change, a Hydra has 2x AP4+/AT5+ and 1x AP5+, while a Skyray has 2x AT6+ Guided (effectively 2x AT5+), 1x AP5+ Ignore Cover, and Markerlights.  I would say that the Hydra has better Secondary Weapons.
- They are both the same speed, but a Skyray is a Skimmer.  Mobility advantage:  Skyray.  (Although every Tau vehicle is a skimmer, that mobility still needs to be considered in points)

Based on this review, I would say that the Skyray is fairly pointed as 75 points, and that the Hunter is the oddity.  While the Skyray has better AA/AT range, the Hydra has better weapons overall.  A Skyray is slightly more mobile.  I believe that the skimmer mobility is pretty close to equalling the better overall weapons of the Hydra.
