Maxipreps and columns (or not?)

Hi all. 
Just run a quality control on a column maxiprep (NucleoBond from 
macherey-nagel). I noticed no difference in the look of the gel bands 
comparing the material I obtained after lysis and neutralization 
(KOAc step, i.e. that what I apply to the column) and the eluate from 
the column. 
So, I just wonder if all this fuss really is necessary (for doing 
transfections) or if simply a direct iPropOH precipitation would do 
it, too. 
Has anyone yet tried the transfection quality of not column or CsCl 
purified plasmids?

The E. coli host I'm using is XL1-blue
