Go for short generally but for some long is better yet it is still better to consider these stuffs too which are given below while deciding brandables.
I shall take your examples itself for the stuffs to consider.
Muvai would be my keep as it targets to lots of other branding too as it does (Ex. Targets to the Moving or Relocating Markets of any sort,also to AI technology other than the driverless tech).Its short (which most brandables target on) and cute and also good to remember and sounds easy to hear and pronounce.
Sensating too does target to a good range of audience but still my goto would be Muvai.
That's just me and my opinion it's your Domain and your decision of what to keep and what to discard.
@Domaindogged Hope this stuff helps you in Length of your Brandables
