Disco's...
I was never a huge fan of the bushings on the TF discos, especially after running them a couple of years. They were approaching the point where I was about ready to press in new ones due to visible wear. Plus it may be just me, but the JKS discos just feel more substantial and of a better quality. I have no beef with TF, just my opinion having had both.

Talking about the end of the locking pins, not the mounting pins, it makes it a bit easier to get the pins started if the holes are packed with mud

I don't think it means JKS's don't break, I just couldn't find anything on them breaking. Also, as you saw in the other pic, the JKS links are adjustable so if your lift goes bigger or smaller, you can adjust them to the exact height you need. They are more needy than teraflex though as you will need to grease them every couple f months. If you don't have a grease gun, you can pick on up at harbor freight for like $20.
Good luck on making your decision.

I've never had JKS discos but I've had Teraflex and would NOT recommend them at all.
First, TF tells you to just "push" out the metal bushing rod like it's very easy thing to do... Without a press or a vise, this was really hard to do since the darn things were seized onto the bushings themselves.
Second, after installation, try to disconnect/connect them on the trail...
you would probably need a crowbar and a sledge hammer to get the discos off! I've heard that if you call TF, they'll send you pins where they've shaved off just a bit to make the whole process easier but why do that? why buy something where you have to call them to send you the ones that works? I really don't understand their method of business.
If there are enough complains about a product, why don't they just send out the product that works rather than having the customer call and ask/wait? Maybe they've learned and are shipping the links with correct sized pins.
Third and lastly, the disco mounting bracket that you install to have the discos tucked away at least for me, would hit the tire when the tire is fully stuffed and turned. Last thing I want on the trail is to have my tire cut because of design flaw from something that i've purchased.
If you don't have rubicon e-disco, I would recommend disconnects that you fully take out rather than the ones like TF where you take the bottom off and tuck them away for storage...

I'd go with the JKS.
I've had three sets of teraflex. One set on my old ZJ that some how bent while connected, mild off roading. Second set to replace them (at my own cost). The bushings only lasted about 20k miles.
Most recent was on my JK. Bushings were shot after about 25k. Zerks came out while driving. (Teraflex did send me some replacements free). I screwed in the replacement and it came out. I've got to think something was wrong with the threads themselves on the links.
They are quite difficult to hook up and take off unless you are on very level ground. I fondly remember carrying a crow bar.
I've honestly never used another brand, but I can't imagine something being any worse, probably about the same or better.
Note: never disconnected them on my JK as it is a rubi.
I now have the rear links up front. Nice and quiet.
