Rear Sway Bar Brand Choice?

I'm just curious do you all think it's important to put a higher/top quality rear track bar on a Jeep JKU Rubicon like a Synergy or would just a Rough Country be fine enough with a 4.5" lift and 37s? Basically, does it matter as much as the front track bar?
 
Most suspension kits will included a rear raised track bar bracket that will allow you to retain the factor track bar.

Believe it or not, factory track bars work great until they don’t and wear out like anything else.

If you do in fact need an aftermarket track bar that’s adjustable, I’d suggest Synergy, Rockjock and Clayton.
Thanks, I always love your advice on here. I found out that my bushings in the track bar now are completely shot, took me a while to really narrow it down but it makes sense since I did have to replace pretty much any bushing that was on it already haha. The previous owner I think put an aftermarket rear track bar in (I can't tell, see pic) but no special bracket to raise it up. I have a pic, ignore the poor paint and dirt underneath, it's a project I'm slowly upgrading and fixing issues on. The one end is fairly seized up as well so I can't really adjust it much.

Based on that pic, you can definitely use a raised track bar bracket due to your lift. That is an aftermarket track bar though.
 
Your rear axle is pushed back way too far. Your control arms are too long. I would start by fixing that.
I haven't changed any of that. How do you know from the pic? I don't mean to question, but I'm curious so I can learn how to tell as well. The pinion angle is correct so I would be a bit concerned with moving it around a ton unless I really have to.
 
Basically I need to shorten the rear control arms until the springs are no longer bowed. In your opinion, should I start with the rear upper or lower control arms or shorten all four of them the exact distance at once? How would you tackle it. :)

As OverlanderJK said, the lowers set your axle position and that should be pretty close to stock, even with a tall lift. Essentially, the jounce stops should make good and solid contact with the axle bump pads at full bump. Upper arms set pinion angle in the rear and caster up front.
