This site states this specific value directly, as one of its five "sensible fit" points: value named, recognisable ingredients over a hidden blend.
This site pairs this value statement with its own no-hidden-proprietary-blend claim — worth reading them together as this site's consistent position on ingredient transparency, rather than two separate, unrelated claims.
Worth noting this framing assumes named ingredients are a value to you — if you specifically prefer a proprietary-blend product for other reasons, this site's own framing suggests you may not be its intended audience.
