Who sells the product? What door type stile are you using? Who hangs the door in a door frame? If wither is from a box store, then neither.

Most lumber yards sell Lynden doors. Need solid core paint grade pre-hung 7' high doors for hallway, bath and pantry. The followingis how they are made according to their website.

Lynden Elemental doors are constructed with a smooth, bevel-grooved high-density fiberboard (MDF) surface that is ready for paint. They are available in either a hollow or solid core and are built with engineered wood, using no-added urea formaldehyde (NAUF) glues for a sustainable construction. The doors feature Stiles and rails, which can be made from MDF or hardboard, and are often designed for easy hardware installation

Tells me absolutely zero about their quailty. If you remeber the Yugo car brand their ad slicks looked good as well. I am not familar with them but honestly a company that offers hollow and solid core doors means they are using hardboard face (even on the solid core), the quality can only be so good from anyone. I never in a millions years will recommend Jeldwen products but their Masonite doors (hardboard face) are as good as the next guy because again there is only so much they can do with them. I would be more interested to know what millwork distributor is pre-hanging each brand and the type of jambs they are using.

The jamb is 5 1/8" primed finger joint double rabbet. I do everything myself at age 83.
