The old Centurion and Champion gear that was previously partially modifiable is now fully modifiable with armor, mod, and enhancement slots. You can also remover the armoring if you like.
The new purchaseable Recruit gear is slightly better than the old Centurion gear was. Compare these two items:
Centurion War Leader's Shield Generator
48 Str
102 End
39 Exp
37 Acc
370 FP
28 Def
Recruit War Leader's Shield Generator
51 Str
106 End
69 Exp
39 Acc
379 FP
30 Def
This item is easy to judge because the stats are the same between the two. Other items have had stat changes so some may prefer the centurion gear if they already have it, even though the net stats are lower. Also there are no set bonuses for the new Recruit gear. Champion gear is superior to the Recruit gear.
