Had the 8900 and was given full value trade on 9400 when 9400 first came out. Also have juki tl2010q. Stitch quality and sewing over seams...juki wins. With the hp needle plate and foot, Janome comes close....juki has no complaints with any thread or needle. Janome takes any thread or needle when piecing but is picky sewing quilt sandwich...only likes Janome purple tip needles. Lighting on juki is useless...had to add lights...Janome lighting pretty good, especially with pull out light over needle; could still use more. Automatic presser foot lift on Janome is a winner...throat space on Janome has it all over juki....i’m glad I have both and prefer the 9400 over the 8900 if only for the auto foot lift.
