My Choice
If I were to choose between these two phones, I would choose the OnePlus 9 Pro. While it is an older phone, the sheer difference in performance, display quality, and camera capabilities makes it a much better all-round device. The higher price is justified by the far superior user experience, especially for demanding tasks, media consumption, and photography. The Samsung A05s is more for those on a very tight budget looking for a basic smartphone that can still be used for everyday tasks. While the Samsung A05s might offer better battery life, the overall experience is significantly compromised in several areas. I personally value a smoother, faster, and more capable smartphone for my needs.
