I´m gonna keep it real with you. I personally do not care what I smell like, I just want it to be as strong as possible. For me the best Performance over-all was Montale Arabians Tonka.
Never owned it (because I'm afraid to judging by the comments) but lots of people say 
Followed is the strongest scent ever created.
For me it's disgusting.
Is amazing, just in love with the scent!
It stays forever!
I don't know about "best" since I haven't compared fragrances against each other based on that criterion. But of the ones I have or tried and like, the most beastly have been (in no particular order):
"Tony Iommi Monkey Special | XerJoff"
For me it's 
Red Tobacco . One spray on the back of my neck and I will smell the whole day like a cherry flavoured shisha. Two sprays already make me nauseous.

Oh yes! Forgot about that one. Red Tobacco is an absolute beast!
Yes, Followed (not to be confused with with 
Follow).
If Followed were a movie character it would be the supernatural entity from the 'It Follows' Movie. It will never leave you alone... If you order a sample, wrap it in plastic. I didn't do it and now my sample stash is 'contaminated'. Now, the scent. Some people get maple syrup and coffee, others get curry and fenugreek. Unfortunately, I get the curry soup...
Almost any Vintage fragrance from 80' and most of 90'
Dighilev - Roja
Rozy (voile de parfum) - vero.profumo
l'Air du dèsert Marocain - Tauer
L'Ame Perdue - le Galion
Kyse Delizia di Marshmallow. That perfume lasts well over 10 hours and it's beautiful.
Another one is Enrico Buccella's Marshmallow.
Megamare is among the strongest fragrances that I’ve owned, along with its two best clones: Lattafa Atlas and Maison Alhambra Megara. A single spray will last more than 24 hours. Al Watanabi Kayaan Classic also has a surprising longevity, though sillage is much more muted.
BERGAMUSK from Orto Parisi is extremely strong and lasts ..........................
Pheromone Eau de Parfum I've got a vintage bottle where all the top notes have long been gone and I'll go years without using it because one spray is... a lot. 😅
