You cant go wrong with either.  
I got a 16 inch. A little bit lighter.
Whatever feels right in your hands, if what you should pick.
Or if you start saying in the middle of the gun store, "this is my rifle, there are many like it, but this one is mine!"[;)]

What do you plan on doing with your new AR?

What ranges do you plan to shoot?

What type of ammo do you plan on shooting?

What kind of accuracy do you want to get out of your rifle?

Is the price a big factor?

Lots of questions, but, there are lots of factors involved. You can almost go bottom of the barrel, and buy a throw-away rifle, or, you can go with a top-of-the-line AR. Most folks find themselves somewhere in the middle.

Shop around, and get the best deal on exactly the rifle that you want.

16" will be more for a close range(0 to 300 yds), rounds on target rifle. Easy to move in close quarters, lighter.

20" will gain you some accuracy(, and allow for longer shotspoint targets well past 500 yds)

Another beauty of the AR is that you can buy another upper to add to your system. So, you can buy a 20" upper now, and add a 16" later, depending on what you decide to do.

Tippie is right.  I favor the longer bbl, unless specific curcumstances call for a shorter one.  If so, change out your upper, and proceed with the mission.

the only advantage to a longer barrel is more velocity for longer range shooting.

Don't forget longer iron sight radius for increased accuracy at all ranges.

Shorter bbl. with longer sight radius.
Perfect.

Almost.  Shorter bbl means less muzzle velocity, and a concomitant lessening of FPE, at a given range, not to mention an overall lessening of effective and maximum ranges.

Still, the dissipator is a damn good compromise.
