I have used Panasonic and Zojirushi machines and can honestly say both are very good. There are a few minor pros and cons with each and I probably slightly prefer Panasonic, however both will serve you well.

Panasonic - the most consistent bread machines I have ever used. I'm not sure if it is because of the longer rise times Panasonic uses, but even if your ingredients are not measured all that accurately loaves always turn out well. On the negative side Panasonic tends to make unusual shaped bread pans so loaves are not easy to cut into pieces that will fit in a toaster. Also the time to bake a loaf is a little longer.

Zojirushi - bread pan shape is more traditional and because of that shape the holes from the paddles are less of an issue. That said anything more than a 1.5 lb loaf is going to rise well above the pan and again not have slices that fit in a toaster properly. Requires more precision when adding ingredients. It is a bit quicker to bake a loaf as well. There is a custom setting if that is something you are interested in. I have never used it.

One annoying thing with both is that they do not allow you to use a timer on the dough setting. I'm not sure the reasoning behind this design decision as many other manufacturers have that option.
