What will you mostly use it for?
The K2 Max takes the lead for gaming, programming, modding and workflows that benefit from remapping or macros. It also has the stronger feature set for office use, including layered acoustic foam and double-shot PBT keycaps. The K3 V2 is the more travel-oriented pick because its low-profile design weighs less. Both offer a compact layout and multimedia keys, so either can suit everyday work if its profile and feature set fit your preferences.
