low efficiency speaker vs. high efficiency speaker?


What are the advantages and disadvantages of high efficiency speaker vs. low efficiency speaker? Does it mean that 93db efficient speaker will sound better than 86db?

Thanks for thoghtful responses.
I want this thread open as long as possible to accumulate your information.
I have Totem Forest that is 87db sencitive.
I currently have Bryston 3b-st to drive them.
I've been offered to audition to Cary Cad 50M tube monoblocks which are 50W/ch. Along with that I've auditioned Quicksilver M60 monos in my current setup and they've literally outperformed my Bryston with clarity of midrange. Bass was a little-bit on the background with no significant difference in details. More clear on upper bandwidth and more musical. Dynamics havn't change at all!!!
I wonder if tube output power is more efficient than SS?
Or maybe this is just my imagination due to a transfer from SS to tubes? Another words is that true that tube amplifiers can drive with less power more efficient than SS?
