The destiny/dream machine are super easy to use. The best features I love are the camera, the wide harp space, the color sorting(wish I had this on my dreamweaver), the onboard scan/digitize feature is fun to play with(it does have limitations). I love the pen and laser on mine which are also available on the dream/destiny. They are the same machine, dream has disney designs, and the destiny has nancy ziemen designs. the dream will have the my custom stitch feature if that matters to you. otherwise they are identical in features and stitch functions. I would go with which company/dealer has the best deal since they are identical if you don't care about the designs. Brother also has the best needle threader on the market if that matters to you. it is awesome. The lighting is super bright and the dream is super quiet, even quieter than mine due to the industrial embroidery arm they put on it from their indutrial line. I would get one if they weren't so expensive but I have test drove them and used them in events at my dealer and they are wonderful. They do have inspirational guides for the babylock version. Also another thing I love that I now can't live without is that muvit foot and multifunction foot pedal. I don't know what features the 15000 has but I know that the brothers and babylocks are amazing. Its up to you to decide which features you love the most.
