First and the most important aspect of ARE is their faculty bomb, that is they explode in a highly tremendous way in which one could never forget the impact they produce. In sense they are a main force to fill the knowledge in its peak. The faculties in combination delivers the complete root canal treatment from its basics to most recent advnaceses.
Now the system (Reciprocating) we use, the best part in think is the canal shaping with least chance of breakage and involving all the isthmus area, and less dentin removal in furcal area of root. The reamer also shaves dentin , and prevents pushing it into the apex and later causing blockage and relocation of the canal orfice, is its best advantage.The cost of the hand piece and reamer system is minimal. So according to me go for the Reciprocating system of EDS.
