No opinion on Armadillo - have not used or seen one.
ATB - own 2 and like them best for water work, because of wider flatter design they seem to ride lower in water and are more difficult for young dogs to pick up on land, only had them for a few months so not sure on smell after time like DFT but am guesing that they will not smell like DFT due to material used to construct. Hard as rock in weather like today (-15 degrees) although what isn't at this temp!
DFT - no issues, like them very much - other than smell over time
