Are microfiber deep-pocket sheets actually durable, or do they pill?

Reviewer consensus is split. Verified-purchase reviewers and several Reddit threads praise budget microfiber options like Utopia Bedding for staying soft through dozens of washes, while other r/Bedding and r/BuyItForLife posters report shrinkage, pilling, and corner-seam failures after a year. Cotton percale and bamboo-derived viscose tend to be rated more durable by specialist communities but cost two to four times as much.
