What I would choose and why

If I were choosing between these two, I would personally lean towards the vivo X100. Here's why:

As a tech journalist, I value cutting-edge technology, superior performance, and a great camera experience. The vivo X100 offers a massive leap in performance with its Dimensity 9300 chipset, and the significantly upgraded camera system is something I'd absolutely appreciate. I'm also not someone who values wireless charging so that doesn't bother me. While the S21 FE is a solid phone, the X100 is so much more impressive in terms of what's going on under the hood, not to mention the display is fantastic. The slightly larger size doesn't bother me, and the increased weight is a reasonable trade-off for the performance and features it delivers.

Ultimately, the best choice depends on individual needs and priorities, but the vivo X100 is the clear winner for anyone seeking the best of what mobile technology currently offers.
