Well as I'm sure you're aware it's when you turn the ANR off that you realise just how much noise it cuts out. Seems much better on the 26.
Also when I started flying the 737-800 my 25 started eating batteries. With the 26 I get a longer battery life on the -800 than I did on other types with my 25 when the battery life was pretty decent.
Can't say I often use the talkthrough function much though
