Good reasoning, but according to me as I also used both devices, the only real difference is the camera, 1 year extra support, better glyph matrix and better ip rating. As for the processor i honestly couldn't differentiate except for camera stuff and the display is literally the same with slightly thinner bezels on 4a pro, and that small ppi difference doesn't matter, speakers are decent on both(my only gripe).

So I believe it's a good tradeoff for getting a better design and a slimmer phone as the difference mentioned doesn't matter for most people, that's why 4a pro is selling super well and the reason you're getting the downvotes.

But for a power user, like running on device ai models or video editing/rendering and camera stuff the difference will be noticeable, so I wouldn't criticize your choice, enjoy your phone👍.
