If you'll be braving the rain, I would get something with a gore shell.

If you'll be out of the rain, go for that Nuptse.

EDIT: Goose down is the best insulator you can find, but it's a natural fibre that will break down over time. If you want something that will last longer, you might want to try a synthetic insulator such as primaloft. But you won't find a synthetic insulated jacket in that price range.
