So many source control

I realize this morning that I need to install tortoise Git to have a better Git Experience (I’m not a Git fan) and after the installation now I have three version of Tortoise


And this remind me of my early age of programming at high school, when I did not know even what a source control system is, now I use 4 of them, TFS, Subversion, and HG and Git for some open source project o_O.
