for me personally, I have only owned and tried a few variations of the dunlop wah pedals since 1990's , but im currently using the wizard wah.
I love the wizard wah for its application with gain, it has a slight boost to it which is good for me, and i also enjoy the sweep spectrum as in the treble side...really cuts thru for me..
For cleans though, i would say the wizard is so-so , I've heard better, but for dirty it is good at what it does.
no idea about the budda wah, purple reminds me of barney
