Gothmog killed Men and Elves by the bucketful in the Dagor Bragollach, the Battle of Unnumbered Tears (where he cut a bloody swath through the armies of Men and Elves) and the Battle of Gondolin. Only exceptional Elves and Men held their own against him and even then, not for very long.
Not as impssive as this.
"There came wolves, and wolfriders, and there came Balrogs, and dragons, and Glaurung father of dragons. The strength and terror of the Great Worm were now great indeed, and Elves and Men withered before him; and he came between the hosts of Maedhros and Fingon and swept them apart." And never has anyone been able to match Glaurung one on one.
Feanor fought Gothmog one on one and was said to have been wounded several times, you also have to remember Feanor had Elves around him in the Dagor Bragollach.
Feanor did not fight Gothmog one on one.
"Thus it was that he drew far ahead of the van of his host; and seeing this the servants of Morgoth turned to bay, and there issued from Angband Balrogs to aid them. There upon the confines of Dor Daedeloth, the land of Morgoth, Fëanor was surrounded, with few friends about him. Long he fought on, and undismayed, though he was wrapped in fire and wounded with many wounds; but at the last he was smitten to the ground by Gothmog, Lord of Balrogs..." Sure Gothmog ended up killing Feanor but there were more Balrogs present at the battle and he was "wrapped in fire" clearly suggesting that numerous Balrogs helped take him down.
