Being a Noldor in itself wouldnt neccessarily translate into being a powerfull warrior. I would say the Eldar in general would apply as more powerfull. Granted, most Eldar in ME at this time were Noldo, and most of these had seen many years of war. By LOTR, there werent a lot of Eldar around ME, but there would be no comparison IMO with any other type elf.
But, as warrior prowess goes, I would submit that there were at least as many (if not more) Sindarin elves who I would rate as high (at least on the warrior skills rating).
Silvan/Avari - eh .... probably quite a few who were way up there on the "ranger" type skills: hunters, trackers etc., that could translate very well into warrior type skill sets. But yea for the most part - better at partying than fighting
Against a Ringwraith, any elf who didnt bring an Eldar to the fight would be sorely tasked.
