<p>Based on the comments, I have set a bounty <a href="https://stats.stackexchange.com/questions/64226/lme-and-lmer-comparison">on the 2013 question</a>, claiming that "The current answer(s) are out-of-date and require revision given recent changes", which is not entirely correct but the closest "bounty reason".</p>

<p>(Now I'd just love for <a href="https://meta.stackexchange.com/questions/124016/line-breaks-paragraphs-for-bounty-text">the bounty text to respect the paragraph breaks I included</a>...)</p>

<p><em>Edit</em>: I just awarded the bounty to <a href="https://stats.stackexchange.com/a/64236/1352">Ben Bolker's original answer</a>, although there was not as much updating going on as I had hoped for. However, <a href="https://stats.stackexchange.com/questions/64226/lme-and-lmer-comparison#comment407306_64236">Ben posted a link to some additional recent thoughts of his</a>, which he may include in his answer at some date.</p>
