I have items from both. I’m not on Instagram -- I found them from nyt write-ups (maybe wirecutter). The quality is really nice. I would compare the quality to room and board, not ikea (and I have furniture from both of those places too!).
I have 2 of these chairs (not the ottoman) from article. They’re so comfortable and have held up great.

And I have this in my dining room from castelry. Much nicer than sideboards I saw at the CP ikea.
