In 5 days, 2 * 5 = <<2*5=10>>10 peaches will ripen.
With the 4 that were already ripe, there will be 14 peaches that have ripened.
Three were eaten, so there will be 14 - 3 = <<14-3=11>>11 ripe peaches left.
There are 18 - 14 = <<18-14=4>>4 unripe peaches left.
Therefore, there will be 11 - 4 = <<11-4=7>>7 more ripe peaches than unripe peaches in the bowl after five days.
