We had a fairly new sewer in our guild and she was having all sorts of problems with her machine. When I went to help her I noticed she had both metal and plastic bobbins and I asked her which came with her machine. When she put in the bobbin that came with the machine she didn't have any problems at all.
I would say if you want to spend time fighting with your machine use what ever you want. If you actually want to sew without problems use what came with your machine.
