It depends on the song and what I am going to play that determines the key signature.

Since I am not very proficient on my wind controller I stay with the simple key signatures C, F, G, D, Bb or their relative minors.

It doesn't matter what key signature if I'm playing guitar or bass as I can play in all keys with these instruments.

I'm a real hacker when it comes to the keyboard so the fewer sharps or flats the better. I can usually figure something out on the keys but it takes a long time.

BobH is a finger picking guitarist so when he comes over the key signatures are usually C, G, D, A, or E.

When JonD comes over we make up key signatures!

If I have to pick my favorite key signatures they would be Em or Am.

PS - I only sing in the key of Z.
