PL still hasn't been topped in my opinion. For me the choice is easy to mostly play PL, due to both the amount of content and friends/guild I have there, but I like the fact that there are other options when I want a change of scenery. DL is cool because I can keep my character "current" with little to no work thanks to the offline missions. SL I don't play as much because it's a "grinder" like PL, and I only have so much time to spend playing games, so I only find myself wanting to play it if there's new content, which there hasn't been for a while.

I only say this just to give an example of "prioritizing" the games, at least for me personally. Your mileage may vary. I'm excited to see what AL will be like.
