The interpretation of the impressions left by the 144 are different from those left by the 114E (fewer groups). By taking impressions you are reducing the number of possible combinations and, in theory, reducing the time it takes to identify the corect pin/lever.
However, it is possible with all P&C's just to use them as pure P&C and work down from the No 1 pin and I know some very competent lockies who prefer this method. The reason for the two types of pins is for the different type of 114 that was issued and has nothing to do with the 114E on which you shoud be using the New 114 Pins.
Any P&C or decoder tool takes time to master and effort spent in the workshop wil be rewarded by less time and possible damage to tools on the door but, a note of caution, this type of tool is not for the sport/amatuer lockpicker and is a serious investment.
