I am mostly a hand quilter, but have recently purchased a mid-arm and frame. I do some easy, fast quilts on that... baby quilts, wall hangings, table runners, etc. But for important projects, I stick to hand quilting.
As for machine quilting, I did have a problem with holding my breath and getting dizzy, but over time it went away. Meandering is more relaxing and helped me get over that.
I've been hand quilting since 1975 and have taught across the country. Maybe it's because I've been doing it so long that it's my favorite. I've noticed lately that there are fewer and fewer hand-quilted quilts in quilt shows, and that makes me sad!
