    Having used both, IMO the performance/easy of use difference is great. AC servo motors FTW. For a non balanced Rig (Stewart Platform etc) a good DC setup is actually not that much cheaper, once you factor in good quality motors, drivers, feedback and power systems. Don't forget that the price of a AC servo motor normally covers also the matched power supply/driver, fitted encoder, cables and connectors.

    I am located in China. On Taobao, I can buy a cheap and stable DC motor driver board to drive my 24V 400W DC motor (the motor price is very low), as well as linear potentiometers with various stroke and low price. Moreover, the price of an 800W DC power supply is only 200rmb. So the cost of DC motor is lower! And this low-cost performance can fully meet my needs.

    Your time/money so the decision is always yours.

    I mean, if there's no big performance gap between the two solutions, why not use a lower cost one? But because I have no comparison, I don't know how to choose.

    Just choose. In a few months, you will want to redo it all again anyway. All sim makers are like that.
