I believe all feigaos, wanderers and hackers are similar in terms of effeciency, but the Aveox ( specially the sensored based ones) are weaker than the others. Probably the most powerful are the 19-22 series of lehners followed by Kontronik's full line of motors( all kontronik motors use segmented magnets) and the Tango is the only motor capable of challenging the 22 series ( the 2230 at least).
