Singer 4411 vs 4423
Summary verdict
Singer lists the same 1,100 spm, 84 W motor, metal interior frame and 6.25 in needle-to-tower figure on both, so this is a feature gap, not a power gap. The 4423 adds 12 stitches, a one-step buttonhole and a built-in needle threader, and the 4411 only wins on a real price gap.
