the more pertinent question is how many machines have YOU test driven?
It honestly doesn't matter what we think, they are both excellent brands, but the machines with in the brands can vary and only you know what you need.
I spent 2 years off and on test driving all the brands (while I saved up to pay cash) so there was no question of buyers remorse for me.
One thing to remember about the Bernina is the cost of the feet. Highway robbery.
