I don't like having two monitors side by side because I find myself looking not-straight for too many hours of the day at my 'primary' monitor. I too used to use an _| shape with one in the centre and one tall one on the side. Now I use a 43" 4k monitor and use most of the middle 2/3rds. I would use an extra wide monitor but they're made excessively wide & short. When playing games I can use 2560x1440 @59 Hz and the monitor knows to do 1:1 pixels so it's only using the centre of the display. I'm not so hardcore I need higher refresh rates--though the buttery smooth scrolling on new Macbooks is nice.
