Choose the AULA F75 Max if you need one board for regular typing, gaming and customization, and value its complete 75% layout and 1000 Hz wired or 2.4 GHz polling rate. If you need both a full keyboard and a dedicated numpad, the F75 Max does not include a numpad, so the Retro18 may suit it as a separate accessory.
