Whenever this topic comes up I always wonder why people feel putting down one machine brand somehow proves that the other is better. All it really does is put those that own the other brand on the defense.
As much as I love my Bernina and would recommend anyone try them out, I understand everyone doesn't like the same thing. I would never be so bold to suggest what I own is the best, and someone else's machine was second class.
My suggestion to anyone looking for a new machine is figure out what features are most important to you, go look at machines with those features and buy the one that you like the best.
