Nope. There is no "better" form of lipsync.
Unless the performance happens under a big red "LIPSYNCING" sign, lipsync is always dishonest.
There has been a weird shift in the discourse with some stans trying to split hairs among different forms of lipsync. I could go on about who is saying what and why during what but I'll keep this brief.
According to them just playing the studio track while the performers mime the lyrics is relatively honest. While the practice of using "prerecorded live vocals," or even just pitch correction and backtrack, is truly immoral and meant to trick the audience.
But no.
Lipsync is always dishonest unless admitted, and it is never admitted. The company PR calls it live, the stans call it live, the idols are careful to keep the mics to their lips and look flustered when they fail to do so.
The trick is still there, just in the form of "OMG they sound just like their recordings."
Besides, performing with backtrack and pitch correction is way tougher than lipsync to pull off, so the narrative is probably just cope from stans of groups that do the latter..
