Why use non-free compilers (Cosmic, etc) instead of SDCC?

[Philipp Krause]

I wonder why some developers choose non-free compilers (IAR, Cosmic, Raisonance, etc) instead of the Small Device C Compiler (SDCC) when targeting the STM8.

I am not representative example (i do only two or three small projects with STM8 per year). But i've choosen Cosmic because it was simple to set up and run toolchain on windows (about one day with zero STM8 knowledge to running program with IRQs etc).
