I personally don't have much experience with Sony Ericsson phones. To me, all Sony electronics (outside of the PlayStations) are always just good, but also always at a price premium, and there is usually better value to be found with another brand. (I will concede that many of their recent products, however, actually feels like they are the best in class again.)
Sony phones are no exception to the rule. I've only seen one Sony phone out in the wild (outside of the Persona 5 anime, where apparently every phone is made by Sony). It was good, had everything I wanted on a phone, but nothing really stands out about it outside of its small size. You would think the company that supplies everyone's camera sensors and makes the best mirrorless camera would, by logic, have the best camera phones as well, but again, nothing about them really stands out.
In conclusion, always good, never exceptional.
Also, last 2 cents, I just can't take the name "Xperia One II" seriously.
I used my Z3 Tablet Compact until it fell apart. I would buy an updated one the very second it was announced.
Overall, I wish Sony was actually competing. It really feels like HQ just forgot this tiny division exists so they keep making phones that feel designed for the idiosyncrasies of the people that work there rather than the market at large. That should be good for a place like here, but they're so uncompetitive on price.
