The Best Calendar App for Power Users, Power Calendar Users

In early December, Fantastical and their parent company Flexibits announced that they were raising the prices from $40 per year to $60 per year. After testing busy Cal cron and calendar 366, as well as several others, nothing came close to Fantastical. None of them have an Excel widget, let alone widgets comparable to Fantasticals. And I'll keep testing cron, that's a relative newcomer, but the Apple calendar integration is a must.
