Agreed. With 445 diodes being multimode they can't be focused to a tight point past a couple of feet whereas a 405 diode can be focused to a tight point even at 20 ft away so between that and the fact that 405 burns well due to better absorption it could be considered better over all. In the end the answer to this question depends on the distance you plan on burning at.I totally agree with clif.
At a distance greater than a few feet the 405 blows the doors off a 445.
Up close, higher power wins.
