Which of these mudd's bundles have the most utility as account unlock?

I'm asking more about the value of having the ships account unlocked, for making different build varieties on different alts.

Because if I really want to fly a ship, I just need it on a single character I want to use it on. If a ship is meta but only for a specific type of build, again I can just have it on the char most suitable for that type of build.

It's still cheaper to get a single promo ship using EC, and I have keys I can sell to fund 2 promo ships anytime, but only enough Zen for 2 bundles this sale.

These are the bundles and the main ship I'm looking at, and my other picks from the bundle:

• Science - Crossfield + Annorax (for fun) + 2 epic
• Through the Ages - Atlas + 4 T6
• Tactics - Mirror Constitution + 4 T6
• Fighter Pilot - Deimos + other ships or 50 keys
• Disco Inferno - D7 + other ships or 50 keys
