Ehm, I have been using Terminal.app on OS X for years now, and probably use it > 50% of my time daily (yay for REPLs), and I never really encountered any problem. The last thing I remember was that in OS X 10.5 I had to change some locale option to have UTF-8 working properly. But that's it. Could you give examples where Terminal.app fails?
