high sensitivity + low impedance vs. low sensitivity + high impedance

OK, so here's a hypothetical.

Speaker Y has a rated sensitivity of 90.5 dB and a nominal impedance of 4 ohms (but it actually drops to 3.2 over some of the range).

Speaker Z has a rated sensitivity of 86 dB and a nominal impedance of 8 ohms (but it's actually 10 ohms or more over much of its range).

For a given amplifier, which speaker is harder to drive?

One thing not mentioned is phase angles.

Oh, I did that in a reply to you just recently, in another thread.

Take out the passive cross-over from the equation, and go active. New challenges, sure, but a range of obvious advantages as well.
