If we are talking about measured distortion in an anechoic room, I've never seen any panel come down as low as the best dynamic drivers, nor have I seen them get as close in smoothness of frequency response or dynamic range as equivalent dynamic speakers.
However!
Panel speakers often integrate much better in a room and provide more detail at the listening location, with less acoustic treatment needed.
So I'm not sure which the OP was asking.
