I have the Lichuan "software" installed on 2 of my machines, both Windows 10. One won't work at all when I try to run it and the other gives errors but still "works". But as you say, the "software" simply allows you to type in the parameter values in a sort of spreadsheet format which can be read and written. It's rather underwhelming but the motor + drive cost was dirt cheap, not least as I got a promotional offer. The features available within the Lichuan are minimal but at least they actually seem to work as servos. Be aware that the fan is always enabled with these and they are noisy.

I also have Yaskawa and DMM Tech servos, both of which have recognisable software for tuning the transient response in a meaningful way. The DMM Techs are pretty reasonable but my early DYN2s are set up more like stepper drives than pukka servos. They are somewhere between hobby and industrial in build quality and features.

The Yaskawas are pretty much the gold standard for industrial servos. The software is almost overwhelming in terms of what it offers and the features in the Sigma drives are also very comprehensive. But at least you have config wizards and tuning tools. One of the key challenges is the Japanese equivalent of Chinglish ie understanding WTF they meant when they wrote the words I'm sure they knew themselves.

The Deltas look close to the Yaskawas, which perhaps isn't a surprise, as they are proper industrial drives too. If you can grapple with the documentation, a Delta or a used Yaskawa might be the sweet spot for me. Depends what you want to do and how much dosh you want to spend....
