Nah, Fingolfin was stated as having been the strongest
Anyway there is a quote calling Feanor the strongest and basically best elf in everything.
"For Fëanor was made the mightiest in all parts of body and mind, in valour, in endurance, in beauty, in understanding, in skill, in strengh and in subtlety alike, of all the Children of Iluvatar, and a bright flame was in him."
I think if Sauron were truly powerful enough to be Morgoth's equal, or more, he wouldn't have served him. Despite all of his cunning, Sauron is a Maia and Morgoth an Ainu, so his service to the original Dark Lord was only proper. Also, Sauron was not the only number 2 guy that served Morgoth, either. It's thought that Gothmog was Sauron's equal, if not a close equal. The Lord of the Balrogs may have lacked the magic that Sauron had, but made up for it with his size, strength, and strategic military capabilities. Gothmog is certainly not a villain that should be overlooked.
