"LO is not enough".....it's more than enough sometime...!Each landing is different.
It all depends of what you need for landing...runway length,condition, exit, weight...
Manual braking might even be the best option in some occasion(light weight, long&dry runway, high speed taxi way...).
Lets remind that the purpose of the auto-brake is to reduce the NUMBER of brake APPLICATION to safe the Brake (carbon), sometime by just using idle reverse you barely need to use the brake to take a high speed taxi way(max 60kts).(autobrake useless in that case).
