What is the hardest key signature to play in and why? - signature metal core wheels

What is the most difficult pitch to play and why? I know because I found myself calling in question to create improvised music in this key. If it depends on what instrument Dime! :] I can play almost all instruments, but my most important and here are played on the piano and guitar. (I Rock / Metal love, but I am totally dedicated to the metal head addictive! I love / classical, jazz, flamenco, etc..)
