those are also t1 units that have the weakest  durability attributes in the game.
high model count, low model hp   with infantry armor.    you don't need a land raider to one shot those squads.  
we are talking about a t3 super unit vs a t1 starter unit.   Not a fantastic comparison if you ask me.  you also inadvertently demonstrated my point with your comment .
"try standing banshees 
near a land raider "  exactly:  you have to be rubbing noses with it for its so-called awesome weapons to be felt.   Now what kind of silly person would  do that?
remember this is t3 , even eldar would be breaking out the prisms / d-cannons and wraith guard by now. those should be the kind of units to make a comparison too .
often the effectiveness of a weapon is not in how much damage it can  do , but  the reliability in which it can deal said damage.  This is why  shoota boy upgrades  tend to be more reliable than say  squad upgrades that  add frag grenades for less skilled players.
the shootaboy squad just flat up adds hp model count  and damage  to an already constant method of damage.  But by all means an eldar plasma grenade used correctly  has far superior damage potential .  Yet  if you miss with it , then all that money is wasted. The same can be said for land raiders,  they are easy to predict and even easier to guard against making their damage unreliable  , thus givin the impression that they are under powered.
