Steam vs GFWL vs Origin. Which one the best And Why

I dont hv much knowledge but , i think Origin is better...coz it sells games at Indian price.{I'm Indian}.
If i hv to , for eg. , buy "The Witcher 2: EE" then on steam it of 42.49$ while on origin its of Rs.999 -> 20$ (approx.)
So almost half the price!!!

But in all other ways like groups,friends,more games and dat all aspects ;Steam is best!!!

1. Steam
   and I don't like any other. I hate Origin. I hate Games for Windows Live.

But I have to admit Origin has best support...

I like Steam the most. But I can't stand people calling Origin pure crap and spyware all the time. Most of them probably haven't even tried it yet. They changed their TOS, and afaik Steam/Valve isn't much better. They for example claim the right to close your account for whatever reason, whenever they want. Is that user-friendly? Not really. Look at Steam stats. They are saving every single action you do on steam, that's for sure.

Steam!
