I love the Bernina feet, they are so simple to change, the stitch plate just pops out with no tools needed, and I prefer the front-load bobbin because I can change it without removing whatever I'm sewing or embroidering to get to it.
When I got my first Bernina I loved it so much that I gave my Janome away immediately and haven't missed it at all.
I agree though about the convenience of the embroidery arm being part of the 11000 and not having a module to store / attach for embroidery. Janome's 11000 hoops are squarer and mostly wider than Bernina's current range (except for the new 830).
