Actualy bomber, when you factor in the ores you save from RLVs, Eden has it much better:
1,000 common * 15 = 15,000
500 rare * 15 = 7,500
(there are about 15 modules in op2)
Costing about 3 times as much as a RLV average. Eden would still have the advantage if it had a small fuel cost of 150 common and 50 rare.
