The Ring has the highest raw stats as usual, but the Bracelet is pretty unique; the Bracelet is a 5* rarity, so it can be leveled up to Lv.50, whereas the other pieces of the set can be leveled up to Lv.40. Up until now, 5* accessories were only obtainable from character quests, which are locked to that specific character. The Halloween Necklace also provides the hybrid of Attack/Defense, while the Earrings provide pure defense; completely opposite of what normal Earrings do, but it does so in double the normal amount.
Also bear in mind the level of importance of Attack vs Defense becomes very relative when you have enough 5* Knights to start synergizing their abilities together. Attack is both a standard and safe way to go, since it's the highest stat we can boost and multiply with equips and abilities, especially when starting out.
However, when it comes to specialized teams, there's no discernible difference between Offensive/Nuking squads vs Defensive/Tanky squads in terms of the damage they output. There's only two basic differences between the two; the first and obvious one is that Offensive Squads deal damage in a shorter timeframe, vice-versa. The second difference is that the Defensive Squads have more opportunities to activate Battle Skills over more turns, which helps to make up for their difference in attack power.
