Free to Play PvP Character - What to Choose for Event Campaign Reward?

I break down a couple of things about choosing my event campaign reward. While it would feel good to grab the Deimos, MWFDC, S31 Sci Destroyer, or Mirror Engle.... I think the smart choice is to choose Lobi and wait for a sale so I can get two ships, such as the Zahl Cruiser for Invincible or the Walker for Obfuscation Screen - choices that benefit all of the builds on my account instead of just one or two.
