I'd agree with this as far as we're comparing the offensive value of a CF vs. Squadron command. I generally value CF commands the lowest out of the four (heresy, I know), because the raw dice and number of attacks from a squadron command usually translates into higher damage output overall (assuming, obviously, that the ship in question has available squadrons within command range).
On the flip-side, there is also an opportunity cost associated with spamming squadron commands. The top list at GenCon was built for maximum damage output, but stayed afloat by using almost exclusively defensive commands, repair and navigate. Spamming squadron commands with a dedicated carrier severely limits the options available for repairing (one token, topping out at 3 repair points for MC-80/AF-II + Redemption boost) or navigating (one token + Nav Team, for changing 1 speed or 1 yaw, or one token + Engine Techs, for changing speed once plus adding one speed 1 maneuver). The trade-off is (hopefully) more offensive firepower through the squadron attacks to destroy attacking enemy ships before the lack of repairs/maneuverability catches up to the carrier.
Well, the reverse could be said. When you're spending Engineering Commands, you're not doing damage
The case on a VSD with an Engineering Command + Token recovers 2 hulls or 3 shields. With an average damage of 3 per 4 TIE Advanced activated, you're effectively negating the Engineerig Command ![]()
Besides, with fighters, you can afford to not spam Squadron Commands every turn. If you expect your squadrons to be tied up in a dogfight, you can afford to have them fight only in the squadron phase (and thus you take an Engineering Command that turn) if you think they can win it. If you can predict the position a ship so that your squadrons will be able to hit it next turn, you can squadron command them into position, get a shot, and get a free shot next turn.
But asking whether fighters/bombers are important or useful is like asking whether CR90s are important. They're just a facet of fleet building
