Vertical lines not being vertical/parallel in an image do disturb our brain much more than horizontal lines not being horizontal/parallel. One reason being our eyes set horizontally on our face.

when photographing architecture or interior I would either go for a one point perspective 1PP (straight on), a two point perspective 2PP(from an angle) and very rarely little for the 3 point perspective 3PP (from an angle and pointing down or up)
I make sure when shooting one point perspective that horizontals and vertical are dead on, can not stand it if they are not. especially if either lines are near the edge of the photo
when shooting 2 point perspective I would point the camera at an angle no less then 25 degrees. If it is less then it goes too much for my liking to a one point
perspective. what I learned way back from an art teacher was that either you do it or you don't, in this case meaning you either shoot straight on or at a strong angle.
if you are not bold in those desicions the photo will weaken. of course this is a self imposed rule which can be broken in the right way.
I think a portfolio should have a good mix of these perspectives as they have different effects on the viewer. One point perspective being more quite, still and resting
and two point perspective being more dynamic.
At this point my preference goes to 65% of the time to a 1PP and 35% to a 2PP. I really love the graphical senses that gets more awakened
in a 1PP, it kind of looks more like an elevation drawing, 2PP are sometimes better to cut through interior spaces and show the dynamic of the space.
