Some people say Mike Tyson was left handed but that's simply not true.
Maybe Oscar De La Hoya? Andre Ward?
Spence is the current best actual southpaw imho. But I think your referring to switch stance punchers. I would probably give it to jacobs af as current fighters. Historically Hagler was actually right handed but fought southpaw his entire career & Hearns was an excellent switch puncher also. But haglers the greatest at the art of fighting the opposite of dominant hand,he did it so he can have far more powerful left hooks the best punch in Boxing which is why Canelos so good atm because his left hook is the best in the business imho like haglers almost, same way gggs jab is the best in the business also.

Jacobs is right handed. I'm strictly talking about naturally left handed boxers who use the orthodox stance like Ward, Cotto, De La Hoya..etc
