1. Buy early MAX
More slots make every later TIER upgrade pay back faster. The optimized first route starts with MAX, then TIER.
The practical answer is to balance Spawn Tier and Max Spawn, then rebirth when your highest owned nuke reaches the current gate.
More slots make every later TIER upgrade pay back faster. The optimized first route starts with MAX, then TIER.
Pure TIER reaches the same gate much later because TIER cost grows faster than MAX cost.
Once you actually own the required nuke tier, rebirth is usually better than delaying for expensive late MAX levels.

Cash Mult, rebirth bonus, friends and event boosts scale the wait times down. They usually do not change the TIER/MAX order.
Raids and city attacks can add bursts, but the stable route still comes from reinvesting into production upgrades.
