The 4423 fits utility sewing when its stitch menu already covers your seams and garment details. A one-step buttonhole and needle threader give it the main convenience features considered here. There is no reason to choose a larger menu merely because it contains more entries.
The linked offer is the Meltwater Blue 4423. Its Meltwater Blue color is stated clearly rather than implying it is the gray version.
The 4432 is worth choosing when a particular stitch in its 32-stitch menu is useful to your projects. Check the stitch chart rather than buying from the difference in totals alone. Its one-step buttonhole and needle threader keep the basic setup similar.
The linked 4432 is the Black Special Edition. Check the manufacturer's current included-accessory list before buying additional feet.
More stitches are not evidence of stronger piercing power. Both need an appropriate needle, suitable thread and a controlled approach to bulky seams.
For the earlier four-step buttonhole decision, read 4411 versus 4423. For heavier fabric, the existing heavy-duty guide explains the limits of domestic machines.
