I recently faced the same dilema. My three options were the Webley Longbow, HW 97k or the Tx200.
I picked the Tx200HC in the end. I read how the AA was better straight out of the box etc but, the fact that the HW and the Tx are so similar means that my ultimate decision was based on AA being British! That may seem a short sighted and outdated reason to pick a product, but I am a patriotic sort of chap and I am also very happy with my choice.
