What will you mostly use it for?
The K70 Max is the stronger fit for gaming and programming when adjustable actuation or dual-trigger input is useful. Its magnetic switch design also gives it an edge for switch experimentation, though standard MX switches will not fit. The BlackWidow V4 Pro's dedicated macro keys and configurable dial make it a better match for command-heavy content workflows. For office use and travel, the shared full-size wired design leaves no clear winner based on the listed features.
