The way I've been taught by music theory prof. and my current guitar instructor were both the same, so I would say this may be the easiest.

b's = BEADGCF

#'s = FCGDAEB


The reason for this is because when writing the key sigs, this is the order you will use for either sharps or flats.

(i.e. Eb major key sig would have the flats starting from left, moving right = Bb - Eb - Ab)

(i.e. D major key sig would be as follows = F# - C#)

Hope this helps even the slightest, man
