The "rule of thumb" is that verticals are noisier because QRN (lightning
crashes, etc.) are generally vertically-polarized. In my experience this is
true on the lower frequency bands (e.g. 160 and 80 meters). 

But there are a lot of other types of noise and noise sources. QRN that is
propagated and radiated from power lines - which tend to be horizontal - may
couple much better into a horizontal wire than a vertical, for example. 

Like all "rules of thumb", whether or not it is true depends a great deal on
the "thumb", as Jim points out.

You may be right, but I suspect that the location of the antenna with
respect to the 
noise is more likely the key.
