SOrry to sound ignorant but I can't remember.

When dealing with ratings for speaker power input:

Say we had 150w at 8ohm

AND

150w at 4ohm

Is there a difference, in other words is one more powerful than the other.

Nope - 150W is 150W.

What IS different is the voltage and current.
For an 8ohm load the voltage would be 34.67V and the current would be 4.33A.

For a 4ohm load, the voltage would be 24.5V and the current would be 6.12A.
