The Nord has a bigger screen, better cpu, more ram if you get that model, bigger battery, faster screen refresh, faster charger, made of better materials (glass back) and the camera(s) are better.
Google took way to long getting the 4A out of the door, if they had pulled their finger out and got this on the the market when it was supposed to before the pandemic it would have been a market hit. Now though? It's very weak against the Nord specs wise.
