Efficiency will only improve by a noticeable margin if you have bad pedalling technique and thus dead spots are a problem. Dead spots shouldn't really be much of a problem at sort of low cadences that you tend to climb fixed as you can focus a lot more on pedalling in circles. If anything the advantage to fixed when climbing is down to the lower weight.
