I liked D, though my current 5.1 system and my current 2.1 system both have something more similar to A.
Voice control would be nice, but not a must-have for me. It would also likely drive up the price, and if it's not the voice assistant a specific person already built their smart home around, an additional expense with no benefit.
The height of these soundbars wasn't mentioned, but if they're taller, they should also come with an infrared relay so the TV remote still works if the soundbar is laid in front of the TV.
Nice to see Anker/Infini really jumping into the soundbar game hard!
