How we assign awards →The differences that matter
- 4.6 kg vs 7 kg → what you lift each time the machine comes out and goes back
- 5 vs 7 buttonhole types → the Singer covers more variants with the same one-step procedure
- Automatic vs semi-automatic needle threader → on the Singer, threading the needle takes one more manual step
Which one to choose
Choose Brother ST150HDH if…
the machine comes out of the cupboard for every job and goes back afterwards: it is 2.4 kg lighter to carry. You give up speed (850 spm against 1100) and buttonhole variety (5 types against 7). The needle threader is automatic.
Choose Singer Heavy Duty 6700C if…
you often sew long seams or runs of different buttonholes: 1100 spm and 7 buttonhole types, with a metal frame. The cost is 7 kg to carry and a semi-automatic needle threader.
