I am just a social dancer

. I don’t take workshops/classes so I can not comment on an instructor’s teaching ability.
IMO, the best social dancers are not known, except by other social dancers. I could list many no names, but probably better to stick with household names.
Out of the known celebrities, I like different dancers for different reasons. For simplicity’s sake, I will break it down to solo/musicality vs partnerwork.
Solo work/musicality: Terry Tauliaut, Vanessa Lacedonia, Alberto Valdes, Eddie Torres Jr, Ezgi Zaman, Magna Gopal, Bersy Cortez, Umberto Nocita, Fadi Fusion, Franklin Diaz
Partnering (ability to lead smooth and connected dances or who is just good at partnerwork): Jorge Ataca Burjos, Panagiotis Aglamisis, Rodrigo Cortazar, Tito Ortos, Jose Diaz, Oliver Pineda, Jariel Garcia, Mitchell Provence, Milton Cobo
People who are just good: Griselle Ponce, Tania Cannarsa, Ella Jauk, Tamara Livolsi, Cecile Ovide, Ana Garcia, Fernando Sosa, Adrian Arellano
Notable mentions who at one point I really enjoyed but who I'm no longer sold on or haven't done anything recently I have particularly enjoyed:
Maykel Fonts, Adolfo Indacochea, Marco Ferrigno, Frankie Martinez, Karel Flores, SuperMario, Alien Ramirez
Took me a while to compile this list. I'm sure it will change.
