title: Comparison between Twitter Bootstrap Gems for Rails
body: <p>What are the advantages and/or disadvantages of the different gems providing Twitter Bootstrap's functionality to Rails? As of the time of writing this question, The Ruby Toolbox <a href="https://www.ruby-toolbox.com/search?utf8=%E2%9C%93&amp;q=twitter+bootstrap">lists the following projects</a>:</p>
  
  <ul>
  <li><a href="https://www.ruby-toolbox.com/projects/twitter-bootstrap-rails">twitter-bootstrap-rails</a></li>
  <li><a href="https://www.ruby-toolbox.com/projects/bootstrap-sass">bootstrap-sass</a></li>
  <li><a href="https://www.ruby-toolbox.com/projects/bootstrap_form">bootstrap_form</a></li>
  <li><a href="https://www.ruby-toolbox.com/gems/less-rails-bootstrap">less-rails-bootstrap</a></li>

  </ul>
  
  <p>And even some others providing partial functionality (e.g. generating forms). How do these gems differ?</p>
  
  <p>P.S. If appropriate, please write about each gem in a separate answer, so that each one can be voted for.</p>
