Sorry I didn't see this earlier.
Personally, I prefer text to be on a column box that's over the background image, with the column color/s complementing the current background image. The column box could also look sharp if slightly transparent, but it depends on the background image. Even a column with a light pattern could look nice, but only as long as the text is nice and clear.
I could see if I can look up some examples if you want.
(The CCGR forum theme is a pretty good example of solid columns that complement the back ground.)
