Well, personally, I find having the freezing point of water defined as zero and the boiling point as 100 quite intuitive and easy to use. To me, due to my experience growing up in Canada (mostly) after the metric change-over, having the freezing point of water at 32 seems quite counter-intuitive. Kelvins are useful for science (is there an aboslute Farenheit equivalent?) but not very intuitive for day to day use.
