In your experience, what's the toughest ship to destroy? I'd like to talk about ships that would actually see play, either casually or competitively, so don't completely discount offense. But the focus is on defense! Be it through green dice, upgrades, or sheer HP. Ships from any or all factions are welcome for discussion as well as any price point. What ship have you struggled to destroy or felt indestructible with?
Edit: Fel is definitely the top choice, but after him what's the most defensive build you've seen?
