High power rating=better speakers?

Just curious what people's thoughts on the relevance of speaker power ratings. Does more = better? What does being able to handle more power mean? Does it mean the speaker can go louder? I am considering a speaker change. My current speakers are rated at 500W max with 91d sensitivity. The ones I am considering buying are rated at 130W with 89 db sensitivity. They are both large floor standing speakers. Should power handling have a part in my purchasing decision when evaluating speakers? I have never really concerned myself with this spec in the past but the difference between the two speakers I am looking is very large and surprising.

Thank you,
