Actually, this is what I think:
 * Tack Sprayer is stronger against stronger bloons, e.g. Pinks
 * Blade Shooter is stronger against rushes, e.g. BTD5 Round 27, Fast cooldown bloons in Battles. Blade Maelstrom can also help destroy rushes (e.g. Rainbow Rush of Doom) since it has unlimited popping power.
