My 97 is a KT, thumbhole stock model, and I am not a huge fan of that style. It's fine off a bench but for offhand, ect i prefer a more traditional stock. Fit and finish on the TX is far superior, I have a walnut stock on my TX and it is outstanding, full crotch grain in the buttstock area. As far as shooting the TX is a little trickier, loading that is, the port is smaller, and the bear trap makes it trickier but I do like any safety feature. Ease of cocking about the same, accuracy is a toss-up . I actually prefer my 77 to the 97, I have it equipped with a hooded diopter on front and an Anschutz diopter on the rear with a Gehmann adjutable iris, so much more fun shooting it offhand, plus lighter weight.
My take is if you want fit and finish go the Air Arms, If you want shooting ability only go the Wierhauch for the price difference. Oh, I forgot to mention that I do not see much difference in the triggers, I can tell a difference in the trigger on my HW97, vs a HW77 and a HW35e and they are all supposed to be the same, so as far as that goes, the trigger will be the luck of the draw, all will be good, some a little better, others not quite as good.
