Not completely a fair assessment. TOS Enterprise (and the A) had 79 episodes and 6 movies for us to learn what she and her sister types cold do. The Galaxy Class had 7 seasons and 1 movie, plus guest appearances on DS-9. In contrast, the Sovereign Class only had 3 movies. In one movie, all the action takes place ON the Enterprise and, in Insurrection
we really don't see much ship-to-ship combat.
I think the Sovereign Class got short-changed for sake of the plot.
