Best for

What will you mostly use it for?

The Agar Mini is the stronger fit in the listed gaming, office, programming and content creation comparisons, with its polling-rate specification, operating-system support and additional firmware options. Travel is a close call: both offer wireless connectivity, but their battery information is presented differently. For modding, both have hot-swap and VIAL, while their extra options take different forms. The Agar Mini offers material and firmware breadth; the Zan 40 offers selectable case, backplate and PCB configurations.

For gaming
