Quick Verdict
Grand Soir is the better perfume overall. It’s sophisticated, warm, and versatile with exceptional longevity. Pegasus is sweeter and more playful, but feels less refined. If you want a unique, cozy amber, go Grand Soir. If you prefer a sweet almond gourmand, Pegasus works.

Scent Profile Compared
Parfums de Marly Pegasus opens with a blast of sweet almond and heliotrope, backed by vanilla and sandalwood. The heart reveals a powdery violet and amber accord. On dry-down, it becomes creamy and slightly woody, with a hint of tonka bean. It’s a smooth, dessert-like gourmand.
MFK Grand Soir starts with a burst of bergamot and lavender, quickly transitioning into a rich benzoin and labdanum heart. The base is a magnificent amber blend with cistus and vanilla absolute. It’s resinous, warm, and slightly spicy. The dry-down is a velvety, almost balsamic amber that lingers close to skin.
Both are sweet but very different: Pegasus is almond-and-vanilla candy, Grand Soir is a sophisticated amber resin.
Longevity and Sillage
Pegasus lasts 6-8 hours with moderate sillage. It projects well for the first two hours then settles into a skin scent. Reapplication may be needed for all-day wear.
Grand Soir is a powerhouse. It easily lasts 10-12 hours with strong sillage for the first 4-5 hours, then gradually fades. One spray on skin can last through a work day and into the evening. It’s one of the longest-lasting amber fragrances I’ve tested.
In terms of performance, Grand Soir clearly outlasts Pegasus.
Best Occasions and Seasons
Pegasus shines in cooler weather: fall, winter, and early spring. It’s great for casual dates, nights out, or cozy days. The sweet, gourmand profile feels playful and youthful. Not ideal for formal or office settings where sweet scents might be overwhelming.
Grand Soir is more versatile. It works beautifully for formal events, date nights, or professional settings due to its refined amber. It’s perfect for fall and winter but can be worn in spring evenings. The warmth and sophistication make it a signature scent option for evening wear. In summer, use sparingly.
Price and Value
Both are luxury niche perfumes. Pegasus by Parfums de Marly typically costs less than Grand Soir by Maison Francis Kurkdjian. However, Grand Soir offers superior longevity, so a bottle lasts longer. The price-to-performance ratio favors Grand Soir if you value longevity. For the exact current price, check current price on Amazon.
Remember that a little of Grand Soir goes a long way, making it more cost-effective over time despite higher upfront cost. Pegasus requires more sprays and more frequent reapplication.
Which Should You Buy?
Buy Parfums de Marly Pegasus if you love sweet, gourmand scents with almond and vanilla. It’s ideal for someone seeking a fun, youthful fragrance for casual wear.
Buy MFK Grand Soir if you appreciate warm, sophisticated ambers with excellent performance. It’s perfect for those who want a versatile signature scent that works for both day and evening, especially in cooler seasons.
If you can’t decide, consider your personality: playful and sweet? Pegasus. Elegant and refined? Grand Soir. Both are high-quality, but Grand Soir edges ahead in complexity and value.
