I prefer single quotes over double quotes because you might be able to
confuse a double quote with two single quotes. Not really an issue,
but just a preference.
I generally choose my strings like so:
Formatting a data model => ERB
Multi line string => Heredoc
Single line string with interpolation => Double quotes
Single line string containing quotes => %q{...}
Anything else => Single quotes
