They've been awesome for me. And I dress up when I get permissions too (or usually just dressed well for work.)
My friend and I have been knocking on doors for about 12 years (hundreds and hundreds of places - quite often 3-4 a day or even more) and I still haven't had an occurrence where I thought having a card would be good. If someone is hard to reach we keep trying, or we're given their number and we get permission that way. I would definitely not leave a card and depend on someone to call me. Plus, I also have to say I just think it looks dumb and doesn't help because there's always going to be people who think you're nuts anyway for wanting to go and try and find stuff.... but not only are you nuts, you have a card too! There's some Detect Dynasty far ya... yeeehaaaa.
