Goose Down Comforter: Supreme Quilts vs. Feathered Friends

For those who have purchased and used goose down comforters from both Supreme Quilts (SQ) and Feathered Friends (FF), I would love to hear your comparison and feedbacks (i.e SQ vs. FF).

What do you like about them and what don't you like about them? Which one feels superior? Which one do you prefer? Thank you.
