The best feature of this toolkit for me is the ability to compile my code without installing any additional tools or libraries as compared with other C/C++ compilers available out there. I have used GCC compiler for years but it took some time before i started using GNU Compiler Collection instead which was not free at all even after purchasing licence from them. It's really hard if you are new user who don't know how things work behind scene to install gcc and gpp etc. But once you get familiarised then everything becomes easier than others because you can just download those packages right away and install directly into your system by double clicking an installer file rather than going through installation wizard step wise.
