Its minimal user interface is what I like best!

The voices are so realistic and its very easy to train on how to pronounce names and product titles

Awedio has so many good surprises. You click a button like "Podcasts" and realize that it offers you a fully-featured podcast with a beautiful UI. You may not have even purchased it for the podcast feature, but once you get it, you're happy to have found it. It also has a great audiobook feature that was a pleasant surprise.
