landscape or portrait?

i took some more photos of my site, particularly photos of the view from the stoops/frontdoors. the first time i went out, my zoom was in and i took landscape pictures. i loaded them up and realized that they didn't match the rest of my set - photos taken last september and october. so i retook the sets (see the slideshows in my sidebar "frontdoorview" and "stoopview") in a portrait orientation zoomed out in order to see the full height of the building and the street in front of it i know i like the landscape images better, but i wonder which one is "truer"?
