Re: Is the USS Vengeance more powerful than the Enterprise E?
No starship is stronger than the power of plot.
On that note, since the Enterprise E as a hero ship and the Vengeance is a villain ship, of course the Enterprise E is going to win. Unless Marcus and his bridge crew have access to Geordi's ocular implants.
