Obligingly, my PP trials and successes:
I love their Prada Iris knock off with Cedar. DS gave me a bottle of the original Infusion d'Iris for a significant birthday, and I haven't finished that but he also sweet talked several samples from the SA. The dupe is IMO better.
I also love several of the Tom Ford dupes. Sahaara Noire was discontinued before I discovered it, but the dupe is lovely. Not too much oudh, but dryly fragrant incense with a hint of rose.
PP Noir de Noir is a black rose, with some oudh. I like this too.
Roses 311 aims to replicate Le Labo Rose 31. I choose this when I fancy a fairly straight forward rose perfume... I like roses, can you tell.
Their version of Chanel's Exclusif Sycomore was once called Seecomore or similar, but apparently has been retitled. This is a hit.
I don't like the PP dupe of PoaL compared to the original, but I bought an oil version not a spray.
I like the oil of Kilian's Imperial Tea better than the spray, which I bought after. Generally not keen on the oil roll ons though. have tucked most out of the way as I rarely reach for them.
The Creed dupes have not cut the mustard for me. Hardly use them; these are the ones that spring to mind.
There's still a huge amount I haven't tried; someone else can take this forward.
