1310 or 1350 Driveshaft Upgrade?

So, when I bought my Jeep, someone had already upgraded the front shaft to an aftermarket one. I think it's 1310, maybe 1350? I know with stock Rubicon, you can just bolt up a 1310 right?

Anyway, is it worth doing the 1350 or should I just upgrade to 1310?

I do highway and off road, nothing really extreme though right now at least.
I have a Jeep JKU Rubicon with 5.13 gears, 37in A/T tires, and 4.5" lift.
 
The one u-joint on the factory front drive shaft is a 1330. Why anyone would downgrade to a 1310 is beyond me.
Oh, I actually didn't know that. I was relying on a Google Search I did that said it was 1310. So maybe my best bet is to get a 1330? I definitely don't want to downgrade haha. I just want to put the RIGHT thing in, so I'm completely open to advice.

Also, here's a screenshot of why I was thinking of the 1310 at all.

There's a lot I know with hot rods and building those but I've never messed with driveshafts much or much 4x4 stuff either. Feel free to educate me on the subject or if you have a video, I'll watch it and learn, doesn't offend me. :)

Well, I would never pretend to know more than what a chart you find on the internet tells you. Me, I can only go off of what I've personally seen, experienced and understand from both. 1310 was the go to u-joint back in the TJ days but for a JK on up (much bigger and heavier vehicle), 1350 is what I personally would upgrade to and for the reason stated.

Wow, the sarcasm... LOL. I was only showing ya something I found in the kindest of ways so I could learn, maybe I was reading the chart wrong or they are wrong or you have a different opinion. I wanted a discussion, I was not trying to insulting your intelligence. Of course real life experience is better than a chart, that's why I asked you about the 1330 thing you mentioned because I know way less than you on this subject and I look up to your videos because I think you're one of the smartest guys around with this stuff. To be fair though, the chart did come from Tom Woods and they are known for their driveshafts, yet I still wanted your real life advice because charts are way different from real life experience. Everything I've asked so far, the community gives me great advice, but you give me a sarcastic response. If it's just out of humor great, I can be really sarcastic too cause it's hilarious, I think that's why I'm a fan, but I am trying to learn too. However, it's almost as if I've offended you somehow for asking a question.

LOL - hang on pal. Yes, I was being sarcastic but not in the way that you took it.

I get that everyone on the internet loves Tom Woods but I've known that guy for a very long time and let me just say, he's not a fan of me and specifically because I showed everyone how he uses substandard china made "gold seal" u-joints and how "well" they actually do out on the trail. The fact that he still recommends 1310s should be all that you need to know about him.

Yeah, I don't know your history with that guy. The chart is from him, but it was someone else on Youtube that had some experience that talked about how if you have gears such as 5.13 you may not need a 1350 so they used his chart as an example. That's what I'm wondering is actually true or not. My Dad was a mechanic for 25 years and is unsure either way too but thinks 1350 might be overkill, but that's simply an opinion. No real facts, just logical guesses. It actually made some sense though, but I wasn't aware that the JKs used 1330 joints already. Everyone in the world wants to give you their advice and most just say to get overpriced components that aren't necessary at all unless you're doing some really extreme wheeling, so I'm putting stuff on my Jeep that's actually necessary. If 1350 or even stronger are needed for my application, then I'm down to do that, if it really is a downgrade, than that's silly like you said.

LOL - so, to that end, and I hope you don't take this the wrong way again but as I stated before, I would never pretend to know as much as some YouTuber that has "some experience". If anything, I would assume he knows way more than me and you should go with whatever he suggests. And to be clear, there is ZERO sarcasm in what I just said (y)

cracks me up some guy always coming up with some chart to be the "smartest" guy in the room then they fail to list the stock driveshaft is a 1330

I've always assumed the guy that makes up a chart did so because they broke something, and it wasn't under "normal" driving conditions.
