get the burton x8 the banana is completely useless. it flops around like a banana peel and the x8 is like x-men its the shizz with optic blast and tiger claws.
get banana if your main thing is park and jib.
if youre more of an all mountain freestyle kinda guy go for the x8.
not really con and pros between the two just depends on what kind of riding youre into.
i will tell you one thing though the banana has btx and burton has the orthodox method of snowboard construction.
