The best brand is the one that meets all Your needs, fits your style, is in your budget.
asking what brand is best is like asking which Car is best. Everyone has their own likes, dislikes, styles & needs.
I own a Viking, a brother, 2 singers, a Janome and a Brenina. All of them are Great brands. I’m sure there are others that people have that are great brands too. It’s best to visit dealers, test drive machines ( just like buying a car) and choose the machine that is best for you.
