Well, of the four you mentioned I can only really comment on the two that I've handled, the TF89 and the B40. Both are quite accurate, though if I had to declare one more accurate I'd say the B40 is. I had a TF89 for a short while, and had gotten to shoot one a decent amount before I got mine, and I liked it. It's a powerful gun, good for hunting. But that power is also wholly unnecessary for shooting targets, and if anything would just make shooting targets more difficult. And, as has been mentioned, it seems allergic to being fired off a rest (or just about any stable surface) for some reason, another minus for shooting targets. As for the B40, it's fairly quiet, still has a good amount of punch to it, and weighs quite a bit more. The weight makes it a very stable shooting platform and isn't really an issue firing off a rest or other object. But I wouldn't want to haul it around hunting. So of those two that I have experience with, I'd lean toward the B40 for your described purposes. I could talk about the TF99 and B26, but doing so would just be hearsay from all the posts I've read here. What I can say is that none of the guns you mentioned is underpowered for hunting, so probably just go with the the one you think you'd enjoy target shooting with the best.
Oh, and as for your post having cooties, it seems like most of the people on the GTA are in the Eastern and Central time zones, so you just posted a bit late to catch the main crowd, that's all. But I'm going to go wash my hands as a precaution anyway :p
