Cons
Con It is not free on Windows Store
Caused by Windows Store way of installing. If you select install trial, you have full use without limit. Don't use Windows Store.
Con Bad character support
Writing normal apostrophes and certain characters is not possible without a certain plugin installed.
Additionally, it does not render all glyphs like most other programs would.
Con Poor high DPI display support
Text is blurry and hard to read on HDPI displays. Both in Windows and Mac.
Con High CPU usage on some Windows 8.1 & 10 versions
HexChat has a long-standing unresolved issue with high CPU usage spikes on key-presses that is noticed in some Windows 8.1 and 10 versions.
Con Doesn't support fingerprint verification for SSL certificate
Doesn't support certificate fingerprint verification for SSL certificates. Hence can't use self-signed certificates for SSL.
Con Miserable IRC font controls (as of 2.13.0.17)
Does its best to avoid putting sensible default font controls in any place where you can get to it. And when it does grudgingly change it, based on system preferences (not local preferences), it does so in an inconsistent and unpredictable fashion.
Con No native VoIP support
While there are plugins there is no built in support for VoIP in Pidgin which is time consuming to implement instead of being baked in from the jump.
