Buying a sewing machine is like buying a car. YOU have to like it for whatever reasons that are important to you. Yes, it is great to ask for opinions but of course each of us will have our own preference for our reasons. Lots of great machines in great brands with tons of features. Me.....i am a Janome gal and I buy Japanese cars.....always have and always will. It is all about the ergonomics, my experience with and the joy from operating both.
Good luck and happy shopping!
