I have a 1236T and chose it over the 1228 for several reasons.
#1, not made in China. I have not been happy with most made in China products, and I don’t want my money going to that country if I can avoid it.
#2, I bought a 3 phase motor version (2hp) so I could use a VFD to control the speed, and have the ability to customize it the way I like. I wasn’t sold on using a DC motor that might be hard to find if it needed replacement, and wasn’t sure how customizable it was with the controls.
#3, it’s a heavier lathe indicating it should be more rigid even though the bed widths are the similar.
#4, NSK P5 spindle bearings. That was a big deal for me, the higher class bearings do make a difference.
#5, I believe the 1236T has better threading options, can’t remember on that, but I did not want to change gears frequently. I mostly do metric, so that was an issue for me that might not be relevant for you.
#6, I like the longer bed, I keep the tailstock on and it never gets in the way. I haven’t needed the length for turning yet, but nice to have that extra length if that day comes.
Made in Taiwan was a big selling point over Chinese, but that does not mean perfect. My lathe had some minor issues, but nothing that was a big issue. Overall, I have not had any significant problems with the lathe and am very happy with it. I’m not sure I would have bought it at the current prices since I can usually find something used in my area, but at the price I paid a couple years ago, I am very happy. I have a thread on my experiences getting the lathe into my basement as well as some of the minor issues I had with it.

Something to consider, the 3 jaw chuck that comes with the 1236T does not have a country or origin on it like my 4 jaw chuck does, so I assume it is from China. It had 0.007” runout, buying a Taiwanese lathe, I would have expected better.
I put an AXA toolpost on my lathe because I had it already. If I was purchasing new, I would go with a BXA due to the better tooling selections with 5/8” shanks, and you can use bigger parting blades. The larger parting blade is getting close to pushing me to upgrade to a BXA.
