I use the standard 1.0 in my modern kettles as well as vintage ones.
Works great in either one. I prefer the welded version over the riveted one.
I would like an XL for my 26 but do not feel that it is worth $90 over the cost of the 1.0 so I just use the 1.0 in the 26.
Sure the xl would run longer and have a larger sear area, but if I need a larger searing area I can achieve that without a slow and sear. If I need longer burn time for low and slow I build a snake.
So for me the original is just fine. Spend the $90 on meat and have fun practicing.
