Clientside vs Serverside hit detection

Admittedly, after RO:OST I only put in about 550 hours of playtime in RO2/RS and even less admin time before taking leave of the series. I've only participated in wave 7 and the open beta weekend of RS2:VN. So if I've overlooked a recent thread or topic about this, please forgive me and point me in the right direction.

I don't recall the option of having client side hit detection in RO2 servers. If there was, I'm sure I had it set on server side.

What is the general consensus today of server admins? Which is preferred and why?.

Thanks,
Floyd (back from a long hiatus)
