Hi, Autoslash.
I mentioned this in the headline but just edited my post to add it into the body: I was referring to the Core (non-Mint) A321.
What I was trying to say was that, according the SeatGuru, the EMS seats vary in terms of the pitch. In other words, some EMS seats have more legroom than others -- again, according to SeatGuru. This was the basis of my question all along. I realize you can see which rows are EMS; what I was asking was which EMS seats have the most legroom.
Regarding whether I think there is a difference between 35" and 37" or even 41", I do, especially the latter. Personally, I am not sure it's worth the $57 for a 2.5hr flight just for 3" more of legroom. 37" is a substantial difference, and 41" is literally on par with all major airlines' first class pitch. In my view, paying $57 for 41" pitch is a no-brainer.
I will try to contact SeatGuru to recommend that they update their information.
