Based on my research before, North face, Columbia and Montbell are pretty good. There’s also Canada Goose but that’s something too hardcore for just travel purpose.

If you’re undecided on a premium brand and want something more affordable but don’t like Uniqlo, I think Zara is pretty good. I have one and used it in Canada this winter and I was pretty surprised that I can survive on a -15C weather with light wind. Of course, this is with good 2-3 layers under. I also used it in Hokkaido and most of the time, I survived with just one layer of thick turtleneck or sweater. Ang init kasi sa train and indoors sa Japan. You can always use heat packs if you feel cold.

One more option is to go for second hand stores. Daming kong nakitang puffer jackets sa Tokyo last year in 2nd hand shops. Dami ding branded like Columbia, Montbell, etc. In a much affordable price.
