The answers would be entirely opinion. There is no one "best" clip out there. It all depends on your personal tastes in women, feet, ticklish response, what type of laughter you prefer, whether you prefer f/f or m/f, etc.
That's kind of like asking what's the best food to eat. Everyone has individual tastes. You just have to browse the hell out of TMF and see which material suits you best! 🙂
