The lower does need more AA, and on the connection ports, is that artifacts? Maybe a better setting in MoI on export (avoid smaller than (.5 is good to start)) may help.
Yup, I have some artefacts on glass area around connections port, mostly because the glass surface overlap the plastic.
It's something I need to improre in my modeling workflow (I did a lot of booleans merge)
I'm doing a brute force rendering and lowering the transparency a little bit to hide this for the moment.
[EDIT]
I have updated the previous rendering, looks much better now
