It all depends on what you are looking to spend and what you like( like anything else)
I think that I may have tried them all except for several( Area 51, HBE, MJM and possibly a few others ) but I was never a fan of
the Bud Wah( which surprised me becuase I love everything else Budda Makes) I like the Fulltone Clyde but not the deluxe. Im not a fan of ANYTHING that morely has to offer. I didnt like the Automagic silver Machine that I tried and none of the Snarling dogs either. Ive heard mixed reviews on the Ibanez weeping demon but never tried it and it has some cool features..
I LOVE my DCR-2SR Dunlop rack wah to death and I love my modded
Vox v847. The 535Q wasnt bad at all. For me, I like a really vocal, in your face wah and the dunlop rack wah does that for me in spades. Honestly, its alot of kwan to drop on a wah, no doubt about it but I love the sound and I love the way that its cleaned up my rig( no signal out to the pedal board, it all stays back in the rack)
Go to GC dude and try them all, even the ones that people dislike. they have a pretty good selection, even some boutique ones depending on where you go. Your ears will decide for you in the end..
