I have a few. I have several rack wahs including the Dunlop 1S, Dunlop 1SR, and two EMB Audio Remote wahs. I love the Dunlops because they're so versatile and you can dial in almost any classic wah sound with them. The EMB wahs are just something totally different so it's not really fair to compare them to anything else. But it's a HUGE HUGE tone with a massively thick sweep. It makes traditional wahs sound like 1940s am radio, haha.
As far as pedals, I think there are a lot of great ones out there but for me personally I love a simple modified Dunlop. Thrown in a red Fasel, add control pots to adjust the low, mid, and high frequencies, and maybe a couple preset peak positions on a rotary switch and you can almost dial in any Dunlop pedal out there.
