But it's not the wrong question. Performance is important to this poster. Compare your answer to, for example, posters #4, #5, and #10, all of whom show the capability and decency to answer the poster's question about performance (not much difference when plugged, significant difference on battery), explain the main benefit is noise and heat, and do it in a friendly, collegial manner (i.e. without talking down to them). That's real wisdom.
Too often people on this forum are more interested in using it as a platform to attempt to show they are superior to others rather than providing actual help.
