Haven’t tried the original issey miyake blue. But I figured this one is better…very strong rosemary perfume and the oil has very good lasting power. Went into work wearing this in the morning a colleague complimented me , he can smell it from a distance (2-3 meters) even with a mask on. Another day at work towards the end , another colleague complimented on the scent , mind you this was 6-7 hours into work so I would say solid 7 hours longevity.
