For grid storage, it's unclear if faster charge/discharge matters. We ended up sizing our batteries to meet wattage demands for our appliances. I wish we had ~ 2x as many kWh as we do. Anker has a home battery whose main selling point is that you can add kWh without adding peak wattage. For use in vehicles, faster charge rates are a big win. Faster discharge probably doesn't matter much for cars (0-60 times are already ridiculously low). They might for drones / planes though.
