Pros and Trade-offs

Your primary need dictates the choice. If you want the smallest, lightest numpad possible to toss in a bag, the EK21 is the clear pick. If you need a desktop-centric tool with arrow keys, navigation cluster, and ergonomic adjustments for long sessions, the TH33's expanded layout and features justify its larger size and slightly higher cost.
