I guess if you never use nested If it "looks" nice but the center alignment does nothing to enhance the meaning of the code or make it easier to understand.
To my way of thinking, it totally obfuscates the purpose and logic structure of the code. I prefer left-justified plus structural indent. Easier to read by taking in stuff in structurally logical gulps.
Uhhhhh. "looks better" - but really, who cares how it looks. The normal indentation is supposed to TELL you something - about hierarchy and belonging. the centered code does nothing, it just looks nice
