Earlier quoted context omitted.
Tabs beat spaces in every single way; - only press a single key instead of tapping 2 or 4 times. - alter their width within your IDE to suit your preferences. - they are "designed" to intent a piece of text with unlike spaces which are "designed" to break words. But use whatever you like as long as it's consistent :)
I prefer tabs BUT ... don't you have to throw out any line-length requirements if you use them?
Imagine everyone setting their preferred tab width and hard wrapping.
That'll be fun for looking at VCS diffs...
