Something to take into consideration regarding red dots on rifles, your eyes. If you are like me and have astigmatism, red dots will start to appear as a starburst. The best red dot sight for me, and it will be different for others is the Trijicon MRO. I suggest you try as many as possible before you make a decision to buy. For pros and cons; the pros, red dots are faster than irons in dynamic shooting situations, can have an amazing battery life, and more durable than you may think. The cons, red dots are expensive and like all optics, you will get what you pay for. I think once you try a quality red dot you will understand why they are so popular. Also, there have been some solid red dots mentioned above, it's like I said try before you buy. What looks sharp and clean to me may not work for you.
