Here it is:

Gate distribution

• Highly unstable (10+2): Devil Reef, Esoteric Order of Dagon
• Medium unstable (6+1): Marsh Refinery
• Hardly unstable (2): Y'ha-nthlei

Clue distribution

• Devil Reef (10+2)
• Esoteric Order of Dagon (10+2)
• Y'ha-nthlei (6+1)
• Marsh Refinery (-)

Devil Reef (10+2) <-10+2-> Esoteric Order of Dagon (10+2)
Marsh Refinery (6+1) -6+1> Y'ha-nthlei

So in summary, we have:

• Devil Reef: Most gates, most clues, next to a vortex, costs $2 to reach
• Esoteric Order: Most gates, most clues, evade check
• Y-ha-nthlei: many clues, next to a vortex, hard to reach ($2) / leave
• Marsh Refinery: Many gates, evade check
