Not "low" quality, but lower relative to Hallberg Rassy, Tartan, and Oyster. that is just my opinion fromlooking at boats and speaking with people. My sense is that they are not as well built re: deck-to-hull joint, hardware sizing, interior joinery. They were not built to as high standards.
I would not be as comfortable in the middle of the Atlantic in Force 8 in an Endeavor as in a Hallberg-Rassy, which is built to cross oceans. Heavy, highly-reinforced hull, extra-well-tabbed bulkheads, beefy hardware. Endeavors were not built for the same usage. it does not make them bad boats, just built for a different audience.
Just my 2 cents. I may be off base.
