I just upgraded, after a year with the HQ Simply 16, to the HQ Amara with ProStitcher. Most important in addition to the machine, is the dealer/rep you purchase from. Free classes, phone/in person support, and caring about you after the purchase. My dealer is there for me 24/7 to answer questions and share in the joy of my first finished quilt. I don’t think I can post dealer names here so anyone would like to know the name of my dealer, feel free to message me.
As as others have suggested, try every machine at the quilt expo and see what feels right to you. I purchased a Janome domestic years ago and it never felt comfortable. The machine was great, just not for me. Sold it and bought a Viking and it felt like home again. Purchase what feels right for you and what you can afford, not what everyone thinks you should purchase.
Good luck!
