I would think you would want the one where the machine can be lowered also. I don't have one - but when setting up my sewing room I had my husband mount counter tops at the proper height in an L to my walls. Now that I have started quilting, this issue of the quilt drag from weight was major. Not enough counter to help support it. I ended up putting another table against my counter and removed everything off the L so I could get the area. Then all I had to suffer with was the bed of the machine being higher than the rest. I would do it differently if I could.
