I honestly think that it would depend on what WP theme you'd be using. Some themes will let you do ANYTHING, and combining that with the crazy amount of plug-ins available for WP, there's no better option. It's faster, easier, and much less hassle!

On the other hand, some themes can be really restrictive. For those types, there's almost nothing that you can do with them that hasn't already been included in the theme, in which case, DW is better, because at least then you have some control. Non-wp sites are less likely to be hacked as well, or so I understand, so there's that benefit as well.

So I guess, in short, it depends on how complicated you want to make things and what theme you're considering.

I know that it was a bit vague, but I hope that this was helpful somehow! XD lol
