Does anyone use the built-in levels in Canon cameras? For landscapes, I usually use the level. It isn't 100% accurate, but it is accurate enough to give you a proper gravitationally level horizon. Sometimes, I find that what I think is my horizon is actually not...it may be the back curve of a lake shore or something. Curved aspects of a scene like that, when leveled, often throw out the "uprightness" of the rest of the scene.
I use the built-in level when I have it (I've got a 5D II & III) and a cheap flash mount bubble level when I don't, and for extra confidence I sometimes double-check against my (somewhat inconveniently located) tripod bubble levels. Despite all this care, I sometimes still end up struggling with leveling in post due to visual mis-cues like the ones you described. It's so frustrating when you get a shot that doesn't look straight even when you know that it is!
