Fastest domestic straight stitch here; the pick if heavy fabric is weekly work.
Heavy duty is a job, not a badge. We rank on motor, presser-foot lift, feed and needle system.

Factory heads sold to home sewists. Each needs a table, a servo motor and a permanent spot, and each does one stitch faster and harder than anything above. Buy the walking foot if your work is upholstery or leather; buy drop feed for flat seams.

The walking-foot industrial upholstery and leather forums recommend first.
True industrial lockstitch for a home workshop, if you have the floor space.

Made-in-Japan industrial straight stitch; needs a table, motor and floor space.
