What will you mostly use it for?
For gaming, both keyboards are a tie due to similar connectivity and the inability to verify performance claims. The M71 V2 wins for office and content creation use cases because it is pre-built, quieter, and has RGB lighting. The A66 is the better choice for programming and modding due to its DIY flexibility and choice of plate materials. For travel, both are tied on portability features like battery and wireless support, though the M71 V2 is lighter.
It's a tie
- Both keyboards support triple-mode connectivity (2.4 GHz, Bluetooth, Wired) for low-latency gaming options.
- Neither product provides specific polling rate or latency figures, so performance claims cannot be verified.
- Both use a hot-swappable design, allowing users to install linear switches suited for gaming.
