Hi guys back with another thread. Im having a problem here. I cant tell whether to call the key of F# or Gb by its real name. Because is there accidentals? There's either two F chords or two B chords. Here's what I mean

(F#maj) G#min A#min Bmaj C#maj D#min (Fdim)

or

Gbmaj Abmin (Bbmin) (Bmaj) Dbmaj Ebmin Fdim

Which one to call it F# or Gb or neither?
