There are many factors that influence the final sound character of speakers, not just sensitivity. To choose a speaker based solely on this one parameter would be folly. That said, picking inefficient speakers limits your choice of amplifiers to higher-powered models.
There are a couple of approaches that work well. You can find speakers that will work well in your room and then find a suitable amp for those speakers. Or you can do the reverse, i.e., decide on an amplifier that you really like and then pick your speakers based on what will work with your amplifier.
Ideally, I'd want the amp/speaker combo to play comfortably without distortion or compression in my particular listening room environment.
