If a piece is in fast 3/4 you'll tap your foot one in a bar. If it's in medium 6/8 you'll tap two in a bar. So notating the same tune at the same speed two different ways will give you the same foot taps.

Here's a piece where it works differently.

Da Lounge Bar

Most of it's in 6/8 (slower than a jig) but it uses hemiola in one section which is better thought of as in 3/4. I can't really imagine tapping your feet through it at all, but if you tried the taps wouldn't all be at the same speed. This is my partial attempt at notating it (I will probably revise this):
