As a 9 year standard Rocket owner I plan to keep it forever and have it become a burden to my children when I'm gone. That said, all the bikes you mention are good bikes. Fun can be had on all of them. For power/weight sake between Rocket and TBird, go Rocket. TBird is nice, but for about the same price/weight the Rocket gives a lot more performance and handling. BTW: I'd go with a Standard or Roadster and dress it up like a touring bike. I prefer the Standard/Roadster to the Touring model due to the gauges, tires and wheels. Between Rocket and Trophy, well thats a little different. Trophy is really nice with all the real touring gizmos. If you plan to do heavy duty touring you should definitely give the Trophy a good long test ride. If you just want a bad ass bike that can do it all, go with the Rocket. Any Rocket that floats your boat.
