So my question is, what commander overall in 2v2 scenario is better, Recon Support Company or Mechanized Company?
Mechanized.
Recon Support requires a three-man squad unlocked, deployed and in range to target a barrage for the 155m strike, whereas Mechanized just need LOS and the requisite munitions for an off-map.
Plus, Mechanized has better options for much of the game in comparison to Recon Support.
In multiplayer trying to close the distance with an I&R Pathfinder is an obvious indicator of a strategy, plus fragile squad means high risk and easy wipe.
