Tabs are the preferred, more efficient and more accessible format, and most people know this. Every golang dev loves just having one tap to indent code, and nobody loves the constant repeat rattle of space indented code.

Seriously though, tabs let you pick what's visually easier for you to read and I've worked with coworkers that struggle when indentation isn't clear.

It's hard to view your opinion as unbiased when you think this is how people indent with spaces.
