My Pick
If I had to choose between these two, I'd go for the Samsung Galaxy Z Fold3 5G, without hesitation. While the price difference is substantial, the sheer technological leap and versatility it offers far outweigh the cost. The foldable screen is a genuine game-changer for both content consumption and productivity, and the performance is simply unmatched. I appreciate the advanced camera capabilities and enhanced connectivity, as well as the build quality. The Z Fold 3 feels like a device that genuinely lives in the future, while the Realme C31 feels like a much more budget-oriented device that has its use cases but is not on par with the premium feel and experience of the Z Fold3.
While I acknowledge the C31's appeal to budget-conscious users and its longer battery life, the Z Fold3's unique capabilities make it a more exciting and versatile device. It is a device that can genuinely enhance my life across all my use cases, and that is what matters most when it comes to selecting technology. If budget were not a factor, I would happily choose the Z Fold3.
