I've had both. Both have good points. Brother has a thing called a pin feed dog position which will help get some fabrics to feed like an even feed foot on a Pfaff. More control on the feed dogs, too - four positions.
Juki feed dogs are either up or down, but Juki has an extra tension knob/feed and speed control
The biggest difference is getting at the bobbin. The Brother needs a door in the table to lift the cover, the Juki doesn't.
The Juki bobbin cover sort of folds up, so if your machine is in an insert on a table, you don't need to move much to access the bobbin. Mine's in a SewEzi table with an insert.
Both have service manuals online. Juki doesn't have a traditional 1/4 inch quilting foot. It's more like a compensating foot. You can buy an aftermarket on. The Juki needle plate is well marked, and so is the Brother.
Don't bugger the foot pedal for the Juki. It has a cutter on it and a replacement is over $200. The other half managed to rewire mine.
I had some trouble with the Brother. I think it was a reboxed return although it was sold as new and any company can put out a lemon. Since it isn't sold locally, I had to get it off line. I did find the Juki locally.
Both machines do very well with any straight stitching. I basted a flower girl satin dress and put the zipper in with the Brother. Far easier than the Pfaff 2170. Both will quilt very well.
Both will FMQ nicely.
