The appeal of Metal 2 and APFS are both pretty big. I waited until 10.13.2 for all the concerns about security and performance issues, but finally made the jump. I am on a mid 2014 MBP and have had no noticeable issues. Most of the people for whom it works aren't posting to Twitter or HN saying "ZOMG everyone! My mac worked fine today. Just like it has been for the last 3+ years."
