Nenya or the Elessar?

[The Might]

One passage in the UT pretty much sums it all up:

Wielding the Elessar all things grew fair about Galadriel, until the coming of the Shadow to the Forest. But afterwards when Nenya, chief of the Three," was sent to her by Celebrimbor, she needed it (as she thought) no more, and she gave it to Celebrían her daughter, and so it came to Arwen and to Aragorn who was called Elessar.

The part with (as she thought) fits in very well as criticism. Basically Galadriel gave up the Elvish, natural way of healing things and instead took the Sauron way, with the Ring of Power. This change fits well with her dreams of glory and power. In the end, I think the Elessar would have ended up with Aragorn anyway, since even had Galadriel kept it for healing purposes, she knew the age of the Elves was approaching its end and that Men could make better use of it.
