There is a big difference in the different brands of servo motors. I researched quite a bit before settling on the SewQuiet 3000. I chose it because it gave me the most features and the most control of any that I looked at. It was not the cheapest, ($140 3 years ago) but it was not the most expensive either. I don't have a problem with the "steps" you talk about, but when you first start sewing, you have to be careful not to push too hard on the treadle too quickly or it will race for a few stitches. After that, it is as smooth as silk.
BTW, just not having to listen to my clutch motors running all day was worth switching to me!
No one lives forever, the trick is creating something that will.
