What the differences mean
Every club the two sets share has exactly the same loft, starting with a 32° 7-iron. On paper there is no distance or trajectory difference: with the same swing, a 7-iron from either set should launch and carry about the same. The real differences are in how the heads are built, how they look at address and how they feel at impact, none of which a spec table can show. Lie angles and lengths match as well, so any fitting adjustment made to one set would carry straight over to the other.
The MX-1000 is a super game improvement iron and the JPX-800 a game improvement iron, so they sit one step apart on the forgiveness scale. The MX-1000 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for high handicaps, beginners and slower swing speeds. The JPX-800 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 10 to 25 handicaps.
The MX-1000 is listed as hollow body with a plasma-welded hot metal face and the JPX-800 as investment cast, split construction across the set. The MX-1000's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the JPX-800, at some cost in feel.
The JPX-800 arrived 2 years after the MX-1000, a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The MX-1000 and JPX-800 share the same lofts on every club on file, so the difference is in head construction, feel and forgiveness rather than trajectory.
