Why Acid Lab wins the first round
Both assets generate similar baseline net flow per production hour: roughly GTA$59.8k for Acid Lab and GTA$58.3k for Bunker. Setup capital differs by more than two times, so similar throughput does not make them similar investments.
Acid Lab also carries a higher solo score and lower friction. For a time-constrained player, that reduces the risk of building inventory that is inconvenient to realize.
When Bunker becomes the better decision
If Bunker is already owned, its historical price should not enter the question of whether to run production today. With setup cost near zero, the relevant comparison becomes margin, time and the alternative use of supplies.
Bunker can also provide utility outside the narrow cash-flow model. Money Meta does not invent a universal GTA$ value for that utility; add it as a separate judgement in your own scenario.
The practical conclusion
A new solo returner should test Acid Lab first as the more resilient entry point. A Bunker owner should test current operating margin before deciding another asset is needed.
