Personally, I don't like noct shield because it is a tower shield and it got low block chance which make it unreliable to me and it also kindda force you into stacking Parry which I also don't like ^^". also I happen to get lucky and got HA shield drop on first T8 kill. (2 month ago) ^^
I going with CRIT/DET personal BIS for PLD. With HA Shield I got more vit and str plus decent block rate and % reduction.

there not really much to compare HA and Novas as it the same shield type.
