Pros and Trade-offs

The Keychron V1 Ultra is the more compelling choice for most users due to its cutting-edge 8000 Hz polling, gasket mount, and longer battery life.

Your final decision should hinge on whether raw performance and a softer typing feel outweigh a more solid, desk-centric construction.
