Random post but I bought the Iommi and Ozzys signature colognes. Here are my thoughts.
I somewhat collect nich fragrances and I'm also a huge sabbath fan. I've known about Ozzys signature scent and purchased a bottle a couple years ago. As for the Iommi they came out more recently and just got them.

No 88 by Czech and Speake - This scent immediately reminds me of an old school style fragrance not afraid to lean slightly feminine. The floral rose notes really come through all the spice and pine. It's truly a night time evening out style fragrance which smells very sophisticated. I'd imagine a wealthy man in London in the 70s to wear this. I easily got six hours out of three sprays. Three being enough not to spice bomb the room out.
Defied Tony Iommi by Xjeroff - This is a heavy on the leather. I am not huge on very leathery fragrances but some I seem to love (Tom Ford) but this one lands right in the middle. This is very spicy to start off then the dry down turns into a new leather sofa. That sounds bad but not really, the woodyness comes out with a very slight rose note. Almost seems like it would be close to the No 88 but the leather over powers most of the notes to me. Two sprays all that's needed or you'll become a leather couch.
Monkey Special Tony Iommi by Xjeroff - This one is a bit of a turn off at the opening for me. I get blasted with a ton of alcohol and spice. Over powers my senses at first to where It hits like smelling a bottle of rum. The dry down is really where it changes and becomes something wearable. It turns into a woody smell that comes off bold, masculine and "fancy" in a way. I enjoyed it the longer I wore it. Also night time time fragrance as this would be extremely overpowering on a hot day.

Overall my favorite is the No 88 by Czech and Speake. The floral notes on top of the strong masculine musk is really enjoyable. It has longevity and enough sillage to make other people notice but not choke them. I can see how and why Ozzy would make this his signature scent for over 30 years. It's very boutique also as you will not find this in stores at least in the states.
As for the Iommis they are enjoyable but the leather and spice is too much for me to start off. Maybe if it was dulled with some heavier gourmand notes, would have helped this for my tastes. Overall they're both great products and I'm a big fan of Xjeroff's many fragrances and own several. I'd just wear these less often than the No88.
That's it. I'm no writer or professional perfume reviewer. I like sampling different fragrances and I like black sabbath. That is all. Feel free to trash me.
