I have both of these machines too. If I had to choose between them, it would take forever because
I use the 600 for piecing and fancy stitches and the 2010 for FMQ. I tried FMQ on the 600 and it was
OK, but like the bigger harp on the 2010. Hope you find a way to choose between the two, because
they are BOTH great machines. I wouldn't even consider any other ones,
