QWS3270 PLUS implements additional configurability, including customizable screen, font, and default settings, as well as support for more than fifteen languages, including English (American and U.K.), Belgian, Italian, Spanish, Norwegian, Portuguese, Swedish, Hebrew, and more).
QWS3270's strength lies in its support for IBM 3270 and Tektronix 4010 terminal emulation. Like EWAN, QWS3270 lacks the ability to run multiple sessions without reloading the program. Overall, QWS3270 PLUS makes perfect sense if you've been looking for a high-quality TN3270 terminal emulator, while the freeware release will still suffice for those that can get by with a bare-bones TN3270 emulator.
Pros: A solid client for IBM 3270 and Tektronix 4010 emulation
Cons: Can't run "multiple sessions" without reloading, needs more flexibility & configurability, outdated feature-set and interface (no major updates in several years)
