You asked for opinions, I apologise for offering one that you do not like.I am a land surveyor by trade. I use maps a lot. It is easy to get turned around even when you have one on hand.
But really this isn't about realism. it is about making the game fun, and making exploration and the effort the PCs put into it worthwhile.
If (general) you don't think mapping is fun, awesome. But what does that add to this discussion?
