Although this is a 3★ CE, don't dismiss it so quickly. Although the stats increase and the buffs it offers can easily destroyed by a 4★ Craft Essence, you cannot deny the versatility in buffs it offers as every servant can benefit from a buff in deck performance.

Not every player has played long and/or hard enough to have enough space in their party to be able to equip 4★ and/or 5★ Craft essences of every one of their servants in the party. Therefore, when you are low on space and don’t know what else to put in your team, this is where this CE shines.
Basically every servant can benefit from this Craft essence but i would recommend servants that can use the critical damage buff so that they can get the most out of this 3★ Craft essence.
