I have a computerized, but low end Brother. I like the stitches, but I don't really use it much, and it's so damn light it jumps.
My Juki is a straight stitch machine, and I love it to death. For me, piecing and quilting are the things I want most to do. So the fancy stuff is wasted on me. I just bought an older Atlas as a backup, and will probably use the Brother even less.
I have friends, however, that love the fancy stitches and things their computerized machines do. So really, you need to think about what you want.
If you want a great workhorse machine, think about buying an older one. Lostn51 (Billy) is a great resource, and helped me pick which one to bid on. They run forever, and are easy to fix and lubricate yourself. Positive things in this economy.
Good luck.
