However one wants to apply this statement (Annals of
Aman, 5, 163), it refers specifically to the harsh journey in the north after being abandoned by
Feanor, and includes a reference to
the Blessed Realm:
"And he [Fingolfin]
and his host wandered long and wretchedly; but their valour and endurance grew greater with hardship; for they were yet a mighty folk, the elder children undying of Eru Iluvatar, but new come from the Blessed Realm, and not yet weary with the weariness of earth."
It's not certain (to me anyway) that this reference is a comparison to the
Noldor or the Eldar . . .
. . .
but in any case, this description hails from the early 1950s, and is part of a longer textual history wherein
Tolkien describes the houses of the
Edain (plus certain references to
Elves), including both earlier and later versions . . .
. . . and in 1958 (the Later
Quenta Silmarillion, Of the Coming of
Men) and 1968 (Of
Dwarves And Men), these later versions no longer contain this statement.

Anyway, in Author's note 5, to Athrabeth
Finrod Ah Andreth:
"They [the Elves]
were thus capable of far greater and longer physical exertions (in pursuit of some dominant purpose of their minds) without weariness; they were not subject to diseases; they healed rapidly and completely after injuries that would have proved fatal to Men; and they could endure great physical pain for long periods."
So whatever else one wants to put forward, it would appear that in these things, at least, Elves outdo Men.
