Synthesis items are really temporary help, the biggest help your units would get is from the spheres equipped actually. I'm pointing this out because it's not necessarily to determine the strength of a unit by themselves as I seen in your spotlights, but I have to admit they're helpful in learning about the game. :)

But yeah the main point is that there's so many spheres out there to help customize your units, like a HP sphere to counter fixed damage, status protection spheres for ailments, BB gauge spheres to help out, or even healing spheres which plays a huge role in Seria GQ. As far as I know, no enemies had ever negated sphere effects directly so I'm sure you can include some sphere choices for your unit spotlights someday. They play a bigger role than units now, especially when you're unlucky with Rare Summons.
