I've heard good things about Fantastical but can't see myself moving away from Sunrise. I've seen a preview of some new hotness they have in the works related to "subscriptions" (@jeremylv already publicly mentioned this in another thread on Product Hunt).

I've been using Fantastical for Mac for years now and same with the iPhone version. I like their design decision to allow you to see multiple calendar views at once - that makes sense for a tablet. $10 does seem a bit steep to me because I usually use my calendar mainly on Mac and iPhone. Definitely worth it though if you want a stock calendar replacement for iPad.
