Machines are very individually specific. Look at all the different machines people on this board love. My suggestion would be to go and try as many as you can. Take small quilt sandwiches with you and any other different fabrics you think you will use and try them all out. We can all give our opinions on the machines we love but again we are individuals and your absolute best bet is to try them for yourself and see what you are most comfortable with. There is no right or wrong for anyone.
