Try them back to back and let us know what difference you feel if any

Alas I fear that I am not a good enough flier to really appreciate the differences. There must be an "ideal" size though, taking into account main blade rpm, gearing ratio, tail blade area, section, type of flying, etc. It's why i was so surprised when i compared them!!
