Another factor is that you receive the bonus the same round you take it. A first turn income tile of 4 coin will generate you 20 coin over 5 rounds. The 4 power tile will give you 24 power which with power actions will give you 21 coins.A net profit of 1 coin.
A first turn ore/power income tile will give you 5 ore and 5 power compared with 24 power which with power actions will give you 6 ore.
A net loss of 2 power.
