mkenobi - I have noted a common misconception.
Most don't want to Upgrade 'Sonics" for various reason, mostly due to no increase in Damage (which is good) - BUT - keep in mind that you are not upgrading "Sonic" but in-fact Upgrading the "Turret Platform" upon which a "Turret" is placed.
PUT SIMPLY - Go ahead and Upgrade the Turret regardless of what it is currently configured as - Sonic, Burst, Rocket, etc., because later you will have the option to SWAP to new Turret Type and perhaps you might want to Swap a Prestige Sonic Turret to a Prestige Burst or Prestige Rocket but if you did not Upgrade the Sonic Turret earlier then you would need to do 2 Actions - Swap + Upgrade - instead of only 1 Action - Swap - if you simply just upgrade all "Turret Platforms".
THAT SAID... IT IS TRUE - that the costs in both Time / Alloy are more at Prestige Level so if you want to Swap first than Upgrade to Prestige that is a valid "Upgrade Strategy".
Hope you understand better...
