I have Paige capos on my guitars. They never leave the guitars except for string changes. I don't find them too fiddly and slow for performing. They're always handy right above the nut and it takes no time to move them to wherever they're required.
On my banjos, I prefer the D'Addario capos that will fit past the 5th string peg, although I seldom capo the banjos past the second fret.
