I will be completely honest...I hate them all.
I agree with this, I really struggled to make it slightly clear.. adding shadow effects made it worse.The only thing I don't like about Devils' is how hard it was to decipher the bottom-right of the text line that goes over the wood pile. When I look at a sigg, I don't like to have to look hard to read it.
To me a good sigg should be able to be read while just glancing past it to the next post on the forum and be instantly distinguishable.... well, I suppose either that or so incredibly flashy and indecipherable that you have to stare at it until you decrypt it. =P
