For children aged 3-6, all three titles seem suitable, but "The Most Magical Day" might be the best choice. It sounds appealing, promising a fun and enchanting story that captures the imagination of young children. The other two titles, while also intriguing, might be slightly more complex or less immediately engaging for that age group.
it depends what you mean by "better". if you want something to play with and show off to your friends , the benchmade, all the way. it could also intimidate a foe... which brings me to my second version of "better": if your looking for selfe defence, the karambit 110%. it is way more effective, and you, with no experience at all, would be able to quickly and effortlessly injure or even kill an attacker. watch out though, karambit's are deadly weapons.
