You want first hand experience, get out and shoot with a 1/16 dot, an 1/8 dot, a fine crosshair (my favorite), and just a dot floating in the middle without a crosshair at all, a dot floating in the middle with the crosshair 1 moa on all sides, a mildot, a Horus, a duplex and several others.
For me, a fine crosshair is the easiest to use. Those stinking dots always seem to float around the ten ring, and for my eye, are very hard to use. You have to have some way of trying before you can decide what you like.
What if you never used a dot and decide to go that route based on what everybody else likes, and then you hate it?
