I would say yes, since I have all of their men's scents and PUH happens to be my most favorite scent, one of the oldest fragrances in my life, my comfort scent, and my "desert island" option (don't laugh, yes it contains your daily dose of vitamin C, cures all ailments, and fixes your flat tires, etc.).
But seriously, Pour Un Homme is very different from the Third Man. It's a soliflore. It's a much leaner and cleaner composition compared to the multifaceted and busy TM. You get a pungent straight forward lavender (some find this to be too harsh at the onset) which settles down quickly to open the way for the ambery vanilla base. TM has the lavender accord but also many other floral components as well as the mossy, musky finish. And have you noticed the brief caramel accord appearing just after the opening?
Don't go with the pyramids you see on PuH. Really, for almost everyone, all that stands out is the lavender and the vanilla. I should state that on my skin, after the initial blast, the lavender becomes a dry herbal lavender and the base isn't all about the vanilla for me but mostly about the amber. Also, by amber, and here's the important distinction for me, I don't mean the sweet generic amber that can mean different things to different houses. I mean an "ambergris" base that turns quite animalic in warmer temperatures on my skin.
This is a universally acknowleged masterpiece and is a model of clarity and classic taste in its simplicity. Very wearable today and I hope you'll try it and will enjoy it. Blind buys aren't safe but since TM was a success for you, I'd say PUH is a *safer* (?) blind buy. Do read the reviews and I'd say go for it. It's so inexpensive you can't go wrong. Go for fresh juice (vintage is not necessary and often has rancid top notes). The color should be a pale but bright green.
In closing, you may notice that TM is sometimes compared to Creed's Bois du Portugal. They're of the same genre, each having their own fans but to me TM is obviously a better value given the quality (vintage or not) and the price.
In the same way, PUH is compared to other lavender compositions such as Creed's Royal Scottish Lavender. If you know this one, it may give you a good idea except PUH is much heavier in the base with the amber/vanilla elements. I still prefer PUH on my skin for even better longevity and of course unbeatable value.
The common complaint about PUH is its longevity. Heavy application usually helps and in fact helps the lavender note to last, which is otherwise normally fleeting.
