Wordpress wins. Here's an example of a clean custom layout using wordpress...
blogcouch.com &
blogotto.com ... I think the clean look goes over well in a professional way. Adding color or ad blocks is all these would need if the clean look is not what your looking for. Anybody looking for a custom wordpress design shoot me a message here or at my gmail email address:
viralspace@gmail.com I will gladly help ya out...I been the guy that wanted a custom blog, but never found a friend to help out so I understand it is frustrating... I don't mind helpin' out...and yes that means for free, but I would'nt stop ya

I do this because I like to help where I had trouble finding free help. Cheers!
