MCR or BFMV????

i need help i want to but a CD and i have narrowed it down to two:
MY Chemical Romance: I brought you my bullets you brought me you love
or
Bullet For My Valentine: The Poison

Well i have MCR's Three Cheers and The Black Parade i know i want to own MCR first CD but i don't know i what to buy it now.
because my friend has been wearing his bullet for my valentine shirt for like the past week i had never heard of them until i saw his shirt i now i think i really like them
i looked them up on iTunes and they only give me 30 sec preview of there song but from what i heard they sound really good.

so please tell me which one you think i should today because i'm so torn between the two.
