I think the Jane is basically a Brother 1500 with Babylock's color scheme.
This is common. When embroidery machines first came out, Brother sold them to different machine companies.
The Bernette Deco, Simplicity, White, Brother were all the same machine. I found that the Deco was the best supported as it was only sold by a Bernina dealer. Some of the others you could buy online or from a catalog. Even though looks differed, the PC 6500 and the Ellure were the same machine. I had both.
If you look at Pfaff's Smart?quilting machine and the Babylock Quest - same machine.
I'd say - try them all, and if decision is close, go with the brand that will give you the best service and repair.
