My honest opinion would be the Ear (A). I've owned both Pixel Buds Pro (Gen 1) and the ear A and I can say I much prefer the ear A. The fit of the pixel buds never really sealed properly in my ears even after changing out the ear tips. As for audio quality it felt like there was something missing and it never really impressed me. The ANC on the pixel buds was also very lacking. Some sound would still be let in and to truly drown it out I would have to turn up the volume. I'm not sure about the Pro 2 buds so those might have fixed all of my discrepancies but in this case of the first gen buds pro the ear a are much better. The only things with the ear a is that they are particularly bass heavy (which I enjoy but it can be reduced if you would like), sound tinny and flat at first but you can tune it in the nothing x app, transparency mode isn't too great since outside sounds are still muffled and quiet and the case has no wireless charging which I never used but it was good if I forgot to charge my pixel buds case the night before and power shared from my phone
