They're one of the few soap makers out there using duck fat as the tallow ingredient, (Oleo calls it their "Canard" base), along with some of the Grooming Dept. soap bases and Bufflehead Soaps. Now, I haven't used either of those soaps, (have a couple GD inbound. Bufflehead might as well be unobtanium it's so small batch), but I have used Oleo's. I would put the performance slightly above Stirling's; caveat that by saying that the reason I would rank it above Stirling is that it is slightly easier to load. All other metrics are very similar. (In my experience of course!)
Vida has quite a few scents out there, so there should be something for just about everyone. She does a lot of cloned scents, (Excursion is based off of YSL La Nuit de L'Homme, Empire is Dior Sauvage, Shiloh is AdP Colonia, for example), but has others that are proprietary to her. Two of the four that I've tried lit my face up (Sandy Cheeks and Melonade), but the other two did not. (Rougere and the Pear-brrr Shoppe soap for WCS)
I point out what has lit me up not to degrade a very good soap base, but just as a buyer beware type of thing. BTW, those two scents that lit me up were AWESOME smelling; and I haven't really read of anyone else getting lit by them.
A lot of people have them up there as one of their top soap bases, but if pressed, I would put them as a tier one box 3. A top scent would take it to a box 2. But I don't think that the performance, at least for me, would ever justify being an elite soap base. More uses and trials might be needed to possible refine judgement.
