Anything which is a bitstream on a slow processor BE has the advantage of being simpeler, see in order processing, anything else it does not matter due to caches and the non issue of adding a few more fets here and there depending on your preferred format and arriving format. (though for debugging hex encoded data I still prefer BE but that is just a personal preference.)
