Wildlands Editions on sale in Xbox store. What edition should I get? Confusing.

Hey all, big Breakpoint fan here who sees the Wildlands editions on sale. The issue is there's so many that I can't tell what I should or shouldn't buy.

Can anyone tell me if the Year 2 Pass, Season Pass or what DLC is worth it?

The base game is $15, the Ultimate Edition is $35, the Year 2 Gold Edition is $23.
