There are various reasons for choosing a particular standard. AICC is a legacy standard and is typically only considered for security purposes or deployment flexibility. The xAPI standard is more advanced; it allows for complex recording of non-standard course activities and can track learning events outside of an LMS (e.g., if watching a YouTube video counts as completing a course). HTML5 is a great replacement for Adobe Flash Player, which is no longer supported.
