IF I had my 'druthers; AA would offer a .20 and HW would ditch the AMBI;
but then I'm a curmudgeon.
I started with TX in 2007 and never noticed the anti-beartrap that seems to bother so many. It gets depressed in an unconscious fashion while shooting. If I had started with HW it would likely bother me.
I have only one HW97, bought a few months back. It, like several other recently purchased HW BB (95X2, and one 98) is a clangy, ratcheting mess. But that is not the fault of the design, it is a fault of whatever is going on with HW as my older HW were not that bad.
I have 3 TX200HC bought between 2007 and 6mos ago. All are very consistently smooth and accurate, and the triggers are surprisingly good out of the box. Counting a large number of HW record triggers over the same period about 1/3 absolutely needed service to equal the AA CD trigger. The triggers are very similar and easy to service once the gun is apart. I obviously own a spring compressor so the 97 isn't that big an issue.
If I shoot offhand, the port issue is not a problem for me but at a bench, I find TX to be fiddly in .177. I am a fumbly old man.
IF HW would pull their socks up, the price difference would be a consideration as either can deliver the mail.
