My Choice
If I were choosing between these two phones, I would choose the vivo X100. While the V21 5G offers the advantages of a lighter form factor and a dedicated macro lens, the X100’s advancements in nearly every category are too significant to ignore. The vastly superior performance, dramatically improved camera system, enhanced display and audio, and significantly longer battery life make it the better option by a large margin.
As someone who values fast performance for seamless multitasking and gaming, appreciates high-quality photography, and frequently consumes media, the X100 better aligns with my needs. The larger, brighter display would be excellent for both viewing media and working outdoors. The additional camera features such as the telephoto lens and cinematic mode would add to my enjoyment of photography. The faster charging and longer battery would also be incredibly convenient for daily use.
While I appreciate the lighter weight of the V21 5G, the benefits of the X100 outweigh the advantages of the former, and I would be willing to tolerate the larger, slightly heavier form factor of the X100 for all the extra features it offers.
