My Choice

If it were up to me, I would choose the Asus Zenfone 9. While I appreciate the Realme's larger screen and bigger battery, the Zenfone's raw performance is too compelling to ignore. I value the snappy user experience and the ability to handle demanding tasks with ease. Also, the small form factor is a huge plus for me, as I dislike the trend of oversized phones. While the lack of a telephoto is a miss, the gimball stabilization is a unique feature that I would find very useful. The enhanced GPS is the icing on the cake for a device that is ultimately designed for power users. The display quality is a plus, with the only downside being the smaller size.
