Batch 2 has better keyboard feel than batch 1. Also batch 1 is missing the esim. I'll report on more later.
I have one of the original (early March) geminis. The keyboard started off a little stiff and I had to get used to it, however after 3 months of use it has bedded in particularly well. I am wondering if the newer keyboards had more tolerance, but wont bed in (ie they will remain consistent). Mine is particularly good now, and I am happily sitting on my deck in glorious Brisbane winter weather touch typing this. One thing to try to see how your keyboard is going.
Run the back of your fingernail across the keyboard in a text document (doesn't matter which). Does every key respond? Are you missing keys?
eg. very quickly running my nail produced (I stopped before backspace, enter etc)

Once you get used to it, you can get a real head of steam up when typing. I am only marginally slower than my full mechanical PC keyboard at work now.
The esim is slightly annoying, however by the time the functionality makes it here, I will be ready for gemini II.
