QLabs is more akin to Powerpoint in its use, it can do some really basic "projection mapping" but its mostly just keystoning and audio playback (You can also do the usual OSC/MIDI/DMX stuff but I've never seen it used or used it myself)
Never actually heard of v-control , it's website is rather light on details.
Isadora and TouchDesigner are very much in the same vain as Ossia
