Both of them are new, so neither is broken in yet.
I have to say that I like the .22 cal B-25. Being already tuned, it loads real smooth and shoots with a nice thud no twang.
My 26 is .177 and not tuned yet. It is not as smooth loading, but there is no twang either.
So, while it should be tuned, it appears to have come pretty good to start with.
I like the B-26 better. So much so that I just ordered a .22 B-26 from MM before there all gone. They are two different animals to me.
Not because my B-26 is .177 but because the trigger action is smoother. Maybe that will change after I polish the trigger on the B-25.
I don't feel two distinct stages on the B-26 trigger like I feel on the B-25. It's a smooth light pull and bang.
On the B-25, the first stage is real light then the second stage stiffer but long. You can anticipate the break, but it's too long for me.
I use the B-26 for target shooting and pests; the B-25 is strictly for tree rats ( that is after I put a few thousand pellets through it for fun), so the two distinct stages work better for me.
Some times you have to back off. The B-26 is quick no room for error.
You can let off the 25 from the second stage and regroup, so maybe the two stages are better in that sense.
It would be nice to be shorter though. ( I can't seem to stress that point enough)
I don't have a chrono yet, so I can only give you the FPS that Mike M put on the B-25 box after he tuned it.

Have you tuned it yet?
They are both real accurate. I was easily hitting a 2" spinner at 40 yds. with the B-26 just resting on a tree limb.
I have only been able to shoot a 10M target in the yard with the B-25, but 5 shot groups where all touching, and I'm not that steady.
Both are scoped of course.
The B-26 is a little lighter, but the B-25 comes up to my shoulder better. I think the stock is a little longer than the B-26.
My B-26 stock is nicely finished. The stock finish is uniform. There are some areas on the B-25 where the bare wood color shows through.
Maybe the luck of the draw who knows. You have to remember that the B-25 is also cheaper, so that may be the difference in fit and finish.
I hope my opinion helps...good shooting.
