I, too, think that moving camera in a roguelike just adds confusion to the player. Highlighting objects/monsters with the cursor should be better.
My personal favorite is centered, too. if performance is an issue, having a "region" within the player can move without scrolling, and once the pc reaches the region border, the view is rebuilt with the pc in a better position, is alright, too. How big this region is, and what exactly is a "better position" depends on the game and the display device, I think, there won't be a general rule.
