try vs andand vs early return (x2)

Which is the preferred way to determine if a chained call is nil? i.e:

1. company.andand.name
2. company.try(:name)
3. return nil if company.nil?; company.name
4. (company or return nil).name

For the last one, you must use the predicate or rather than || to make the return work correctly.

class NullCompany
  def name
    'no company'
  end
end

company = some_logic? ? Company.new(some_data) : NullCompany
company.name
