4 link or 3 link

There are no true 3-link setups available for the rear of a JK without requiring you to remove your factory gas tank and relocate it to the back. Unless you trailer your Jeep, I would not recommend it. There are 3 link setups up front available but, they are essentially a 4-link kit minus one upper control arm. While there are some advantages to it, I prefer the added strength and redundancy of just a normal 4-link setup. If you're going for the kind of big flex EVO coil overs will give you, I would recommend getting the EVO long arm kit as it comes with arms and joints made for big flex. That, or modify what you have or another kit to use johnny joints on both ends of the arms.

What's the deal with this one? I saw an ad for it, is it a true 3 link?

Yes, it is a true rear 3-link but, because it's reversed, it does change the angle if your pinion as your axle cycles up and down. Maybe not too much of a proble but something that is there. Also, the front end is still a radius arm design.
Not exactly as they still retain the use of track bars. Also, the amount of flex you have is for the most part determined by the length of your shocks. A true 3 links can help this along by offering less bind but, it'll still be limited by the shocks it runs.

So will the three link setups like the one from rockcrawler give more articulation than a longarm four link setup or is it more of a gimmick

No. I wouldn't say it's a gimmick per se but, you can only have as much flex as your shocks will allow and depending in what kit you're comparing it to, it may or may not have a greater amount of flex. Does that make sense?
