I think you may have just encountered a bad device. There's nothing I can find that shows the three devices use different techniques to arrive at the SOC. I have two AiLi meters. I realized I'd be pulling a large number of amps and would require a larger shunt so I got the bigger one and just swapped out the shunt and not the head unit because the head units looked identical. It turns out it wasn't and I was not getting consistent readings with the new shunt and the old head unit. Once I replaced the head unit too, everything was fine.
Do you think it would be more accurate if the meters counted Amp hours?
