There is a reason that Valve delays the acquisition of the orange portal in both Portal and Portal 2: if the player got access to the orange portal first, they wouldn't even bother getting blue afterwards - it's that good!
Sure, the orange portals looks better than the blue one. And yes, it sounds better too but its real quality can be found in its mythos.
Orange portal was long oppressed, controlled by a maniacal artificial intelligence; however, it was able to escape into the freedom of player-control, becoming more that it ever was and granting freedom to a human being. It's better than a person!
Now I know what you're thinking: blue portal was oppressed too. I hasn't always been player controlled. You may even be thinking that orange could never have been free without the aid of blue.
And to that I say, "You must think of me as arrogant for assuming to know what you're thinking." but I also say, "You small minded fool!".
The orange portal gives blue portal it's purpose! Without orange, blue would be a shiny blur on a wall in the back of one of Aperture's labs.
Blue is arrogant, always needing to be first. It thinks it's better than you (it told me so).
Orange portal is kind. It is loving. And It is my best friend.
