Here are a few facts that get mentioned when you get tx vs ps threads, better than all the different personal opinions
I think that most would say the PS is the best looking airgun in production but the things to consider are that the PS action is basicly a HC action with a concealed lever and that lever set up is not without faults, have you seen this

But the worst bit for me is the bolt that attaches the linkage to the cylinder as I like to dismantle my gun a lot and this bolt can wear and come loose

But I still like the PS as it is the last of the old concealed lever type left in production
The TX is hard to fault and I like the HC, the mk 3 HC can and does win world championships and also if you want it for back garden plinking you can fit a proper silencer and if you are strong enough to handle the weight the cocking effort should be no bother at 28 lbs.
