dB effeciency vs speaker configuration


I want to know the different caracteristics of speaker. Which one of the following technical data would give better musique, less difficulties to the power amp ? Which would give a better match and sound with stereo tube power amp, and, second with a solid state power amp ? Speaker with air vent, or sealed speaker? Speaker with 4 ohm or 8 ohm ? Speaker with 87 dB or 95 dB effeciency ?

I won't claim to be an expert, but I would say that if you can find the display of impedance and phase across the audio spectrum of any given speaker, you should be able to determine whether or not an amp will be able power it. Though, you need to be able to understand what it is displaying.
Just my 2 cents until brighter minds chime in...
I will defer to Almarg, and Atmasphere, who are probably the best qualified to answer here on Audiogon.
