Excellent work once again from Perfume Parlour. As you can see in the picture, I own the original Creed Wild Vetiver and have compared it directly against both Perfume Parlour's Avalanche Vetiver Grove 13ml EDP and 10ml perfume oil, which are also shown.
To my nose, the Perfume Parlour version is around 90% similar in the opening, with the resemblance increasing to roughly 95% in the drydown. The overall scent profile is captured extremely well: the bright citrus-spice opening is bridged by the rose into the green, woody vetiver character of the original very convincingly.
The remaining 5-10% difference is mainly in depth, texture, and development. The original Creed feels more layered and dimensional, with individual facets appearing and receding as it develops. That gives Wild Vetiver a much more refined, sophisticated, and intriguing character. Avalanche Vetiver Grove is comparatively more linear and less nuanced, although the underlying scent profile remains remarkably close.
Given the enormous difference in price, the Perfume Parlour version is an easy recommendation on value. You are getting most of the Wild Vetiver experience for a fraction of the cost.
That said, I would not say it makes the original completely redundant. If you particularly love this fragrance profile and want to experience the extra depth and refinement that Creed provides, I would still recommend getting at least a 5ml or 10ml decant of the original. For everyday wear, however, Avalanche Vetiver Grove gets impressively close and makes far more economic sense.
