One looks more like IB Viper. I would suggest your take one rhizome of each and grow them side by side. This way they will have the same light, soil, water, etc. and then compare height, standards open or more closed, and beards both on new blooms and older blooms. PBF in some varieties is always there and in others seems to come and go year to year.
Since you have it growing in different locations that may be what is causing the slight differences. Good luck.
