My Choice
I would choose the Samsung Galaxy A15 5G.
Reasoning:
While the A42 5G has its merits in video capabilities and selfies, the practical advantages of the A15 5G are more compelling for daily use. The significantly better display (higher resolution, higher brightness, and 90Hz refresh rate) enhances the overall user experience, particularly for tasks like web browsing, social media, and watching videos, all of which are activities I do frequently. Additionally, the faster charging is a valuable convenience, and the more modern OS ensures that I get the latest software and security updates. These practical benefits, along with the slightly better overall performance make the A15 5G a more compelling choice for my daily usage patterns. The advantages of better front camera, 4K recording and better slow-motion on the A42 are not significant enough for my needs to overcome the daily usage benefits of the A15.
